Permanent Magnet Synchronous Machine (PMSM) and Induction Machine (IM) are the main components of drive trains of electric and hybrid vehicles. These machines have very good performance in healthy operation mode, but they are not redundant to ensure safety in faulty operation mode. Faced with the continued growth in the demand for electric vehicles in the automotive market, improving the reliability of electric vehicles is necessary over the lifecycle of the electric vehicle. Multiphase electric machines respond well to this constraint because, on the one hand, they have better robustness in the event of a breakdown (opening of a phase, opening of an arm of the power stage, intern-turn short circuit) and, on the other hand, better power density. In this work, a diagnosis approach using a neural network for an open circuit fault or more of a five-phase induction machine is developed. Validation on the simulator of the vehicle drivetrain, at reduced power, is carried out, creating one and more open circuit stator phases showing the efficiency and the reliability of the new approach to detect and to locate on-line one or more open phases of a five-induction machine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle%20drivetrain" title="electric vehicle drivetrain">electric vehicle drivetrain</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20drives" title=" multiphase drives"> multiphase drives</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20machine" title=" induction machine"> induction machine</a>, <a href="https://publications.waset.org/abstracts/search?q=control" title=" control"> control</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20circuit%20%28OC%29%20fault%20diagnosis" title=" open circuit (OC) fault diagnosis"> open circuit (OC) fault diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title=" artificial neural network"> artificial neural network</a> </p> <a href="https://publications.waset.org/abstracts/143890/a-neural-network-approach-for-an-automatic-detection-and-localization-of-an-open-phase-circuit-of-a-five-phase-induction-machine-used-in-a-drivetrain-of-an-electric-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143890.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">208</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18327</span> An Equivalent Circuit Model Approach for Battery Pack Simulation in a Hybrid Electric Vehicle System Powertrain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suchitra%20Sivakumar">Suchitra Sivakumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajime%20Shingyouchi"> Hajime Shingyouchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshinori%20Okajima"> Toshinori Okajima</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyohei%20Yamaguchi"> Kyohei Yamaguchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Kusaka"> Jin Kusaka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The progressing need for powertrain electrification calls for more accurate and reliable simulation models. A battery pack serves as the most vital component for energy storage in an electrified powertrain. Hybrid electric vehicles (HEV) do not behave the same way as they age, and there are several environmental factors that account for the degradation of the battery on a system level. Therefore, in this work, a battery model was proposed to study the state of charge (SOC) variation and the internal dynamic changes that contribute to aging and performance degradation in HEV batteries. An equivalent circuit battery model (ECM) is built using MATLAB Simulink to investigate the output characteristics of the lithium-ion battery. The ECM comprises of circuit elements like a voltage source, a series resistor and a parallel RC network connected in series. A parameter estimation study is conducted on the ECM to study the dependencies of the circuit elements with the state of charge (SOC) and the terminal voltage of the battery. The battery model is extended to simulate the temperature dependence of the individual battery cell and the battery pack with the environment. The temperature dependence model accounts for the heat loss due to internal resistance build up in the battery pack during charging, discharging, and due to atmospheric temperature. The model was validated for a lithium-ion battery pack with an independent drive cycle showing a voltage accuracy of 4% and SOC accuracy of about 2%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery%20model" title="battery model">battery model</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20electric%20vehicle" title=" hybrid electric vehicle"> hybrid electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title=" lithium-ion battery"> lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20model" title=" thermal model"> thermal model</a> </p> <a href="https://publications.waset.org/abstracts/113330/an-equivalent-circuit-model-approach-for-battery-pack-simulation-in-a-hybrid-electric-vehicle-system-powertrain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113330.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">298</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18326</span> Optimization by Means of Genetic Algorithm of the Equivalent Electrical Circuit Model of Different Order for Li-ion Battery Pack </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Pizarro-Carmona">V.

Jimenez-Bermejo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this article is to optimize the Equivalent Electric Circuit Model (EECM) of different orders to obtain greater precision in the modeling of Li-ion battery packs. Optimization includes considering circuits based on 1RC, 2RC and 3RC networks, with a dependent voltage source and a series resistor. The parameters are obtained experimentally using tests in the time domain and in the frequency domain. Due to the high non-linearity of the behavior of the battery pack, Genetic Algorithm (GA) was used to solve and optimize the parameters of each EECM considered (1RC, 2RC and 3RC). The objective of the estimation is to minimize the mean square error between the measured impedance in the real battery pack and those generated by the simulation of different proposed circuit models. The results have been verified by comparing the Nyquist graphs of the estimation of the complex impedance of the pack. As a result of the optimization, the 2RC and 3RC circuit alternatives are considered as viable to represent the battery behavior. These battery pack models are experimentally validated using a hardware-in-the-loop (HIL) simulation platform that reproduces the well-known New York City cycle (NYCC) and Federal Test Procedure (FTP) driving cycles for electric vehicles. The results show that using GA optimization allows obtaining EECs with 2RC or 3RC networks, with high precision to represent the dynamic behavior of a battery pack in vehicular applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li-ion%20battery%20packs%20modeling%20optimized" title="Li-ion battery packs modeling optimized">Li-ion battery packs modeling optimized</a>, <a href="https://publications.waset.org/abstracts/search?q=EECM" title=" EECM"> EECM</a>, <a href="https://publications.waset.org/abstracts/search?q=GA" title=" GA"> GA</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle%20applications" title=" electric vehicle applications"> electric vehicle applications</a> </p> <a href="https://publications.waset.org/abstracts/124223/optimization-by-means-of-genetic-algorithm-of-the-equivalent-electrical-circuit-model-of-different-order-for-li-ion-battery-pack" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124223.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18325</span> Simulation of Surge Protection for a Direct Current Circuit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Luis%20Ferrer%20Penalver">Pedro Luis Ferrer Penalver</a>, <a href="https://publications.waset.org/abstracts/search?q=Edmundo%20da%20Silva%20Braga"> Edmundo da Silva Braga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the performance of a simple surge protection for a direct current circuit was simulated.

The battery dynamics and the model parameters vary under different working conditions, such as different temperature and state of charge (SOC) levels, and therefore online parameter identification can improve the modelling accuracy. This paper presents a way of online ECM parameter identification using a continuous time (CT) estimation method. The CT estimation method has several advantages over discrete time (DT) estimation methods for ECM parameter identification due to the widely separated battery dynamic modes and fast sampling. The presented method can be used for online SOC estimation. Test data are collected using a lithium ion cell, and the experimental results show that the presented CT method achieves better modelling accuracy compared with the conventional DT recursive least square method. The effectiveness of the presented method for online SOC estimation is also verified on test data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20circuit%20model" title="electric circuit model">electric circuit model</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20time%20domain%20estimation" title=" continuous time domain estimation"> continuous time domain estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20integral%20filter%20method" title=" linear integral filter method"> linear integral filter method</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20and%20SOC%20estimation" title=" parameter and SOC estimation"> parameter and SOC estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=recursive%20least%20square" title=" recursive least square"> recursive least square</a> </p> <a href="https://publications.waset.org/abstracts/67718/online-battery-equivalent-circuit-model-estimation-on-continuous-time-domain-using-linear-integral-filter-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67718.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">383</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18323</span> Equivalent Circuit Model for the Eddy Current Damping with Frequency-Dependence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhiguo%20Shi">Zhiguo Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng%20Ning%20Loong"> Cheng Ning Loong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiazeng%20Shan"> Jiazeng Shan</a>, <a href="https://publications.waset.org/abstracts/search?q=Weichao%20Wu">Weichao Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study proposes an equivalent circuit model to simulate the eddy current damping force with shaking table tests and finite element modeling.

Since the birth of life on this planet, there has been a quest undertaken by the living beings to analyze, understand and harness the precious natural facts of the nature. In this quest, one of the greatest undertaken is the process of harnessing the naturally available energy. Scientists around the globe have discovered many ways to harness the freely available energy. But even today we speak of “Power Crisis”. Nikola Tesla once said “Nature has stored up in this universe infinite energy”. Energy is everywhere around us in unlimited quantities; all of it waiting to be harnessed by us. Here in this paper a method has been proposed to harness earth's electric field and transmit the stored electric energy using strong magnetic fields and electric fields. In this paper a new technique has been proposed to harness earth's electric field which is everywhere around the world in infinite quantities. Near the surface of the earth there is an electric field of about 120V/m. This electric field is used to charge a capacitor with high capacitance. Later the energy stored is allowed to pass through a device which converts the DC stored into AC. The AC so produced is then passed through a step down transformer to magnify the incoming current. Later the current passes through the RLC circuit. Later the current can be transmitted wirelessly using the principle of resonant inductive coupling. The proposed apparatus can be placed in most of the required places and any circuit tuned to the frequency of the transmitted current can receive the energy. The new source of renewable energy is of great importance if implemented since the apparatus is not costly and can be situated in most of the required places. And also the receiver which receives the transmitted energy is just an RLC circuit tuned to the resonant frequency of the transmitted energy. By using the proposed apparatus the energy losses can be reduced to a very large extent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacitor" title="capacitor">capacitor</a>, <a href="https://publications.waset.org/abstracts/search?q=inductive%20resonant%20coupling" title=" inductive resonant coupling"> inductive resonant coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=RLC%20circuit" title=" RLC circuit"> RLC circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20of%20electricity" title=" transmission of electricity"> transmission of electricity</a> </p> <a href="https://publications.waset.org/abstracts/25302/harnessing-earths-electric-field-and-transmission-of-electricity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25302.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">373</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18321</span> Experimental Validation of a Mathematical Model for Sizing End-of-Production-Line Test Benches for Electric Motors of Electric Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emiliano%20Lustrissimi">Emiliano Lustrissimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Bonifacio%20Bianco"> Bonifacio Bianco</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastiano%20Caravaggi"> Sebastiano Caravaggi</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Rosato"> Antonio Rosato</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A mathematical framework has been designed to enhance the configuration of an end-of-production-line (EOL) test bench. This system can be used to assess the performance of electric motors or axles intended for electric vehicles. The model has been developed to predict the behaviour of EOL test benches and electric motors/axles under various boundary conditions, eliminating the need for extensive physical testing and reducing the corresponding power consumption. The suggested model is versatile, capable of being utilized across various types of electric motors or axles, and adaptable to accommodate varying power ratings of electric motors or axles. The maximum performance to be guaranteed by the EMs according to the car maker's specifications are taken as inputs in the model. Then, the required performance of each main EOL test bench component is calculated, and the corresponding systems available on the market are selected based on manufacturers’ catalogues. In this study, an EOL test bench has been designed according to the proposed model outputs for testing a low-power (about 22 kW) electric axle. The performance of the designed EOL test bench has been measured and used to validate the proposed model and assess both the consistency of the constraints as well as the accuracy of predictions in terms of electric demands. The comparison between experimental and predicted data exhibited a reasonable agreement, allowing to demonstrate that, despite some discrepancies, the model gives an accurate representation of the EOL test benches' performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20motors" title="electric motors">electric motors</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicles" title=" electric vehicles"> electric vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=end-of-production-line%20test%20bench" title=" end-of-production-line test bench"> end-of-production-line test bench</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model"> mathematical model</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20tests" title=" field tests"> field tests</a> </p> <a href="https://publications.waset.org/abstracts/185756/experimental-validation-of-a-mathematical-model-for-sizing-end-of-production-line-test-benches-for-electric-motors-of-electric-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185756.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">50</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18320</span> Analysis of Reliability of Mining Shovel Using Weibull Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anurag%20Savarnya">Anurag Savarnya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The reliability of the various parts of electric mining shovel has been assessed through the application of Weibull Model. The study was initiated to find reliability of components of electric mining shovel. The paper aims to optimize the reliability of components and increase the life cycle of component. A multilevel decomposition of the electric mining shovel was done and maintenance records were used to evaluate the failure data and appropriate system characterization was done to model the system in terms of reasonable number of components. The approach used develops a mathematical model to assess the reliability of the electric mining shovel components. The model can be used to predict reliability of components of the hydraulic mining shovel and system performance. Reliability is an inherent attribute to a system. When the life-cycle costs of a system are being analyzed, reliability plays an important role as a major driver of these costs and has considerable influence on system performance. It is an iterative process that begins with specification of reliability goals consistent with cost and performance objectives. The data were collected from an Indian open cast coal mine and the reliability of various components of the electric mining shovel has been assessed by following a Weibull Model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reliability" title="reliability">reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=Weibull%20model" title=" Weibull model"> Weibull model</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20mining%20shovel" title=" electric mining shovel"> electric mining shovel</a> </p> <a href="https://publications.waset.org/abstracts/8913/analysis-of-reliability-of-mining-shovel-using-weibull-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8913.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">513</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18319</span> New Series Input Parallel Output LLC DC/DC Converter with the Input Voltage Balancing Capacitor for the Electric System of Electric Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kang%20Hyun%20Yi">Kang Hyun Yi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a new parallel output LLC DC/DC converter for electric vehicle. The electric vehicle has two batteries. One is a high voltage battery for the powertrain of the vehicle and the other is a low voltage battery for the vehicle electric system. The low voltage is charged from the high voltage battery and the high voltage input and the high current output DC/DC converter is needed. Therefore, the new LLC converter with the input voltage compensation is proposed for the high voltage input and the low voltage output DC/DC converter. The proposed circuit has two LLC converters with the series input voltage from the battery for the powertrain and the parallel output low battery voltage for the vehicle electric system because the battery voltage for the powertrain and the electric power for the vehicle become high. Also, the input series voltage compensation capacitor is used for balancing the input current in the two LLC converters. The proposed converter has an equal electric stress of the semiconductor parts and the reactive components, high efficiency and good heat dissipation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle" title="electric vehicle">electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=LLC%20DC%2FDC%20converter" title=" LLC DC/DC converter"> LLC DC/DC converter</a>, <a href="https://publications.waset.org/abstracts/search?q=input%20voltage%20balancing" title=" input voltage balancing"> input voltage balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20output" title=" parallel output"> parallel output</a> </p> <a href="https://publications.waset.org/abstracts/31896/new-series-input-parallel-output-llc-dcdc-converter-with-the-input-voltage-balancing-capacitor-for-the-electric-system-of-electric-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31896.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1051</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18318</span> Magnetic Simulation of the Underground Electric Cable in the Presence of a Short Circuit and Harmonics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Nour%20El%20Islam%20Ayad">Ahmed Nour El Islam Ayad</a>, <a href="https://publications.waset.org/abstracts/search?q=Wafa%20Krika"> Wafa Krika</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelghani%20Ayad"> Abdelghani Ayad</a>, <a href="https://publications.waset.org/abstracts/search?q=Moulay%20Larab"> Moulay Larab</a>, <a href="https://publications.waset.org/abstracts/search?q=Houari%20Boudjella"> Houari Boudjella</a>, <a href="https://publications.waset.org/abstracts/search?q=Farid%20Benhamida"> Farid Benhamida</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to evaluate the magnetic emission of underground electric cable of high voltage, because these power lines generate electromagnetic interaction with other objects near to it.

The arc furnace operating will be modeled at different power conditions of steelworks. The paper will describe how to determine the increase in voltage fluctuations caused by working in parallel arc furnaces. The analysis of indicators characterizing the quality of electricity recorded during several cycles of measurement made at the same time at three points grid, with different power and different short-circuit rated voltage, will be carried out. The measurements analysis presented in this paper were conducted in the mains of one of the Polish steel. The indicators characterizing the quality of electricity was recorded during several cycles of measurement while making measurements at three points of different power network short-circuit power and various voltage ratings. Measurements of power quality indices included the one-week measurement cycles in accordance with the EN-50160. Data analysis will include the results obtained during the simultaneous measurement of three-point grid. This will determine the actual propagation of interference generated by the device. Based on the model studies and measurements of quality indices of electricity we will establish the effect of a specific arc on the mains. The short-circuit power network’s minimum value will also be estimated, this is necessary to limit the voltage fluctuations generated by arc furnaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arc%20furnaces" title="arc furnaces">arc furnaces</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20flicker" title=" long-term flicker"> long-term flicker</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement%20and%20modeling%20of%20power%20quality" title=" measurement and modeling of power quality"> measurement and modeling of power quality</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20fluctuations" title=" voltage fluctuations"> voltage fluctuations</a> </p> <a href="https://publications.waset.org/abstracts/75673/electric-arc-furnaces-as-a-source-of-voltage-fluctuations-in-the-power-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75673.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">289</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18315</span> Modelling and Technical Assessment of Multi-Motor for Electric Vehicle Drivetrains by Using Electric Differential</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdel-Monem">Mohamed Abdel-Monem</a>, <a href="https://publications.waset.org/abstracts/search?q=Gamal%20Sowilam"> Gamal Sowilam</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20Hegazy"> Omar Hegazy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a technical assessment of an electric vehicle with two independent rear-wheel motor and an improved traction control system. The electric differential and the control strategy have been implemented to assure that in a straight trajectory, the two rear-wheels run exactly at the same speed, considering the same/different road conditions under the left and right side of the wheels. In case of turning to right/left, the difference between the two rear-wheels speeds assures a vehicle trajectory without sliding, thanks to a harmony between the electric differential and the control strategy. The present article demonstrates a complete model and analysis of a traction control system, considering four different traction scenarios, for two independent rear-wheels motors for electric vehicles.

The imminent retirement of electric vehicle (EV) batteries after approximately eight years underscores the critical need for their redirection towards recycling, a task complicated by the current inadequacy of recycling infrastructures globally. A potential solution for such concerns involves extending the operational lifespan of electric vehicle (EV) batteries through their utilization in stationary energy storage systems during secondary applications. Such adoptions, however, require addressing the safety concerns associated with batteries’ knee points and thermal runaways. This paper develops an accurate mathematical model representative of the second-life battery packs from a cell-to-pack scale using an equivalent circuit model (ECM) methodology. Neural network algorithms are employed to forecast the degradation parameters based on the EV batteries' aging history to develop a degradation model. The degradation model is integrated with the ECM to reflect the impacts of the cycle aging mechanism on battery parameters during operation. The developed model is tested under real-life load profiles to evaluate the life span of the batteries in various operating conditions. The methodology and the algorithms introduced in this paper can be considered the basis for Battery Management System (BMS) design and techno-economic analysis of such technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=second%20life%20battery" title="second life battery">second life battery</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicles" title=" electric vehicles"> electric vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=degradation" title=" degradation"> degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a> </p> <a href="https://publications.waset.org/abstracts/179296/mathematical-modelling-and-ai-based-degradation-analysis-of-the-second-life-lithium-ion-battery-packs-for-stationary-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179296.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">65</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18313</span> Modeling and Simulation of a CMOS-Based Analog Function Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madina%20Hamiane">Madina Hamiane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modelling and simulation of an analogy function generator is presented based on a polynomial expansion model.

The specific weighting factors are calculation, the linear regression dependence of specific losses in semiconductor frequency converters are presented depending on the values of the rated current. It is revealed that with increase of the carrier frequency PWM improves the output current waveform, but increases the loss, so you will need depending on the task in a certain way to choose from the carrier frequency. For task of optimization by criterion of the minimum electrical losses regression dependence of the electrical losses in the frequency converter circuit at a frequency of a PWM signal of 0 Hz. The surface optimization criterion is presented depending on the rated output torque of the motor and number of phases. In electric drives with field regulated reluctance machine with at low output power optimization criterion appears to be the worst for multiphase circuits. With increasing output power this trend hold true, but becomes insignificantly different optimal solutions for three-phase and multiphase circuits. This is explained to the linearity of the dependence of the electrical losses from the current. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=field%20regulated%20reluctance%20machine" title="field regulated reluctance machine">field regulated reluctance machine</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20electrical%20losses" title=" the electrical losses"> the electrical losses</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20power%20circuit" title=" multiphase power circuit"> multiphase power circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20surface%20optimization%20criterion" title=" the surface optimization criterion"> the surface optimization criterion</a> </p> <a href="https://publications.waset.org/abstracts/46140/power-circuit-schemes-in-ac-drive-is-made-by-condition-of-the-minimum-electric-losses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46140.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">294</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18311</span> Chaotic Response of Electrical Insulation System with Gaseous Dielectric under High AC and DC Voltages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arijit%20Basuray">Arijit Basuray</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is well known that if an electrical insulation system is stressed under high voltage then discharge may occur in various form and if the system is made of composite dielectric having interfaces of materials having different dielectric constant discharge may occur due to gross mismatch of dielectric constant causing intense local field in the interfaces. Here author has studied, firstly, behavior of discharges in gaseous dielectric circuit under AC and DC voltages. A gaseous dielectric circuit is made such that a pair of electrode of typical geometry is used to make the discharges occur under application of AC and DC voltages. Later on, composite insulation system with air gap is also studied. Discharge response of the dielectric circuit is measured across a typically designed impedance. The time evolution of the discharge characteristics showed some interesting chaotic behavior. Author here proposed some analysis of such behavior of the discharge pattern and discussed about the possibility of presence of such discharge circuit in lumped electric circuit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20insulation%20system" title="electrical insulation system">electrical insulation system</a>, <a href="https://publications.waset.org/abstracts/search?q=EIS" title=" EIS"> EIS</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20dielectric" title=" composite dielectric"> composite dielectric</a>, <a href="https://publications.waset.org/abstracts/search?q=discharge" title=" discharge"> discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=chaos" title=" chaos"> chaos</a> </p> <a href="https://publications.waset.org/abstracts/103867/chaotic-response-of-electrical-insulation-system-with-gaseous-dielectric-under-high-ac-and-dc-voltages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103867.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18310</span> Nonlinear Passive Shunt for Electroacoustic Absorbers Using Nonlinear Energy Sink</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diala%20Bitar">Diala Bitar</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Gourdon"> Emmanuel Gourdon</a>, <a href="https://publications.waset.org/abstracts/search?q=Claude%20H.%20%20Lamarque"> Claude H.

An electroacoustic absorber consists of a loudspeaker coupled to an electric shunt circuit, where the membrane is playing the role of an absorber/reflector of sound. Although the use of linear shunt resistors at the transducer terminals, has shown to improve the performances of the dynamical absorbers, it is nearly efficient in a narrow frequency band. Therefore, and since nonlinear phenomena are promising for their ability to absorb the vibrations and sound on a larger frequency range, we propose to couple a nonlinear electric shunt circuit at the loudspeaker terminals. Then, the equivalent model can be described by a 2 degrees of freedom system, consisting of a primary linear oscillator describing the dynamics of the loudspeaker membrane, linearly coupled to a cubic nonlinear energy sink (NES). The system is analytically treated for the case of 1:1 resonance, using an invariant manifold approach at different time scales. The proposed methodology enables us to detect the equilibrium points and fold singularities at the first slow time scales, providing a predictive tool to design the nonlinear circuit shunt during the energy exchange process. The preliminary results are promising; a significant improvement of acoustic absorption performances are obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electroacoustic%20absorber" title="electroacoustic absorber">electroacoustic absorber</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple-time-scale%20with%20small%20finite%20parameter" title=" multiple-time-scale with small finite parameter"> multiple-time-scale with small finite parameter</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20energy%20sink" title=" nonlinear energy sink"> nonlinear energy sink</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20passive%20shunt" title=" nonlinear passive shunt"> nonlinear passive shunt</a> </p> <a href="https://publications.waset.org/abstracts/82596/nonlinear-passive-shunt-for-electroacoustic-absorbers-using-nonlinear-energy-sink" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82596.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">220</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18309</span> Analysis of SCR-Based ESD Protection Circuit on Holding Voltage Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yong%20Seo%20Koo">Yong Seo Koo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Ho%20Nam"> Jong Ho Nam</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Nam%20Choi"> Yong Nam Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae%20Yeol%20Yoo"> Dae Yeol Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung%20Woo%20Han"> Jung Woo Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a silicon controller rectifier (SCR) based ESD protection circuit for IC.

The main advantages of AIA arrays are the simplicity of fabrication, low cost of manufacturing, and the combination between free space power and the scanner without a phase shifter. The integrated active antenna modeling is the coupling between the electromagnetic model and the transport model that will be affected in the high frequencies. Global modeling of active circuits is important for simulating EM coupling, interaction between active devices and the EM waves, and the effects of EM radiation on active and passive components. The current review focuses on the modeling of the active element which is a MESFET transistor immersed in a rectangular waveguide. The proposed EM analysis is based on the Method of Moments combined with the Generalised Equivalent Circuit method (MOM-GEC). The Method of Moments which is the most common and powerful software as numerical techniques have been used in resolving the electromagnetic problems. In the class of numerical techniques, MOM is the dominant technique in solving of Maxwell and Transport’s integral equations for an active integrated antenna. In this situation, the equivalent circuit is introduced to the development of an integral method formulation based on the transposition of field problems in a Generalised equivalent circuit that is simpler to treat. The method of Generalised Equivalent Circuit (MGEC) was suggested in order to represent integral equations circuits that describe the unknown electromagnetic boundary conditions. The equivalent circuit presents a true electric image of the studied structures for describing the discontinuity and its environment. The aim of our developed method is to investigate the antenna parameters such as the input impedance and the current density distribution and the electric field distribution. In this work, we propose a global EM modeling of the MESFET AsGa transistor using an integral method. We will begin by describing the modeling structure that allows defining an equivalent EM scheme translating the electromagnetic equations considered. Secondly, the projection of these equations on common-type test functions leads to a linear matrix equation where the unknown variable represents the amplitudes of the current density. Solving this equation resulted in providing the input impedance, the distribution of the current density and the electric field distribution. From electromagnetic calculations, we were able to present the convergence of input impedance for different test function number as a function of the guide mode numbers. This paper presents a pilot study to find the answer to map out the variation of the existing current evaluated by the MOM-GEC. The essential improvement of our method is reducing computing time and memory requirements in order to provide a sufficient global model of the MESFET transistor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20integrated%20antenna" title="active integrated antenna">active integrated antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=current%20density" title=" current density"> current density</a>, <a href="https://publications.waset.org/abstracts/search?q=input%20impedance" title=" input impedance"> input impedance</a>, <a href="https://publications.waset.org/abstracts/search?q=MESFET%20transistor" title=" MESFET transistor"> MESFET transistor</a>, <a href="https://publications.waset.org/abstracts/search?q=MOM-GEC%20method" title=" MOM-GEC method"> MOM-GEC method</a> </p> <a href="https://publications.waset.org/abstracts/82843/electromagnetic-modeling-of-a-mesfet-transistor-using-the-moments-method-combined-with-generalised-equivalent-circuit-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82843.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">198</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18307</span> Numerical Analysis of 3D Electromagnetic Fields in Annular Induction Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abderazak%20Guettaf">Abderazak Guettaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The mathematical models of the physical phenomena interacting in inductive plasma were described by the physics equations of the continuous mediums.

In order to validate models, we compare the results obtained by an equivalent circuit models with numerical simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metamaterials" title="metamaterials">metamaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=SRR" title=" SRR"> SRR</a>, <a href="https://publications.waset.org/abstracts/search?q=HIS" title=" HIS"> HIS</a>, <a href="https://publications.waset.org/abstracts/search?q=CPW" title=" CPW"> CPW</a>, <a href="https://publications.waset.org/abstracts/search?q=IDC" title=" IDC"> IDC</a> </p> <a href="https://publications.waset.org/abstracts/32369/modeling-and-simulation-of-practical-metamaterial-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32369.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">429</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18301</span> Design of 900 MHz High Gain SiGe Power Amplifier with Linearity Improved Bias Circuit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guiheng%20Zhang">Guiheng Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Zhang"> Wei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun%20Fu"> Jun Fu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yudong%20Wang"> Yudong Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A 900 MHz three-stage SiGe power amplifier (PA) with high power gain is presented in this paper. Volterra Series is applied to analyze nonlinearity sources of SiGe HBT device model clearly. Meanwhile, the influence of operating current to IMD3 is discussed. Then a β-helper current mirror bias circuit is applied to improve linearity, since the β-helper current mirror bias circuit can offer stable base biasing voltage. Meanwhile, it can also work as predistortion circuit when biasing voltages of three bias circuits are fine-tuned, by this way, the power gain and operating current of PA are optimized for best linearity. The three power stages which fabricated by 0.18 μm SiGe technology are bonded to the printed circuit board (PCB) to obtain impedances by Load-Pull system, then matching networks are done for best linearity with discrete passive components on PCB. The final measured three-stage PA exhibits 21.1 dBm of output power at 1 dB compression point (OP1dB) with power added efficiency (PAE) of 20.6% and 33 dB power gain under 3.3 V power supply voltage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20gain%20power%20amplifier" title="high gain power amplifier">high gain power amplifier</a>, <a href="https://publications.waset.org/abstracts/search?q=linearization%20bias%20circuit" title=" linearization bias circuit"> linearization bias circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=SiGe%20HBT%20model" title=" SiGe HBT model"> SiGe HBT model</a>, <a href="https://publications.waset.org/abstracts/search?q=Volterra%20series" title=" Volterra series"> Volterra series</a> </p> <a href="https://publications.waset.org/abstracts/62323/design-of-900-mhz-high-gain-sige-power-amplifier-with-linearity-improved-bias-circuit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62323.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">339</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18300</span> Biofouling Control during the Wastewater Treatment in Self-Support Carbon Nanotubes Membrane: Role of Low Voltage Electric Potential</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chidambaram%20Thamaraiselvan">Chidambaram Thamaraiselvan</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Dosoretz"> Carlos Dosoretz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work will explore the influence of low voltage electric field, both alternating (AC) and direct (DC) currents, on biofouling control to highly electrically conductive self-supporting carbon nanotubes (CNT) membranes at conditions which encourage bacterial growth. A mutant strain of Pseudomonas putida S12 was used a model bacterium. The antibiofouling studies were performed with flow-through mode connecting an electric circuit in resistive mode. Major emphasis was placed on AC due to its ability of repulsing and inactivating bacteria. The observations indicate that an AC potential >1500 mV, 1 kHz frequency, 100 Ω external resistance on ground side and pulse wave above the offset (+0.45) almost completely prevented attachment of bacteria (>98.5%) and bacterial inactivation (95.3±2.5%). Findings suggest that at the conditions applied, direct electron transfer might be dominant in a decrease of cell viability. AC resulted more effective than DC, both in terms of biofouling reduction compared to cathodic DC and in terms of cell inactivation compared to anodic DC. This electrically polarized CNT membranes offer a viable antibiofouling strategy to hinder biofouling and simplify membrane care during filtration. <p class="card-text"><strong>Keywords:</strong> <a
