In order to meet the needs, we need to generate the power using alternate method. In this paper, a presentable approach is developed by analysis and can be implemented by utilizing heat energy, which is generated in numerous ways in some of the rural areas in India. The thermoelectric generator unit will be developed by combing with control circuits and converts, which is used to light the LED lamps. The temperature difference which is available in the kitchens, especially the exhaust pipes/chimneys of wooden fire stoves, where more heat is dissipated into the atmosphere, can be utilized for electrical power generation. Hence, the temperature rise of surroundings atmosphere can be reduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermo%20electric%20generator" title="thermo electric generator">thermo electric generator</a>, <a href="https://publications.waset.org/abstracts/search?q=LED" title=" LED"> LED</a>, <a href="https://publications.waset.org/abstracts/search?q=converts" title=" converts"> converts</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a> </p> <a href="https://publications.waset.org/abstracts/109415/electrical-energy-harvesting-using-thermo-electric-generator-for-rural-communities-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109415.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">142</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">1829</span> Direct Drive Double Fed Wind Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vlado%20Ostovic">Vlado Ostovic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An electric machine topology characterized by single tooth winding in both stator and rotor is presented. The proposed machine is capable of operating as a direct drive double fed wind generator (DDDF, D3F) because it requires no gearbox and only a reduced-size converter. A wind turbine drive built around a D3F generator is cheaper to manufacture, requires less maintenance, and has a higher energy yield than its conventional counterparts. The single tooth wound generator of a D3F turbine has superb volume utilization and lower stator I2R losses due to its extremely short-end windings. Both stator and rotor of a D3F generator can be manufactured in segments, which simplifies its assembly and transportation to the site, and makes production cheaper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20drive" title="direct drive">direct drive</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20fed%20generator" title=" double fed generator"> double fed generator</a>, <a href="https://publications.waset.org/abstracts/search?q=gearbox" title=" gearbox"> gearbox</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet%20generators" title=" permanent magnet generators"> permanent magnet generators</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20tooth%20winding" title=" single tooth winding"> single tooth winding</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20power" title=" wind power"> wind power</a> </p> <a href="https://publications.waset.org/abstracts/152197/direct-drive-double-fed-wind-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152197.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">190</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">1828</span> Thermoelectric Generators as Alternative Source for Electric Power</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20C.%20Ding">L.

This work utilizes D-mannitol (DM) matrix as the suitable PCM for coupling with thermoelectric generator to achieve the middle-temperature solar energy storage performance at 165℃-167℃. DM/MWCNT composite phase change materials prepared by ball milling not only can keep a high phase change enthalpy of DM material but also have great photo-thermal conversion efficiency of 82%. Based on the self-made storage device container, the effect of PCM thickness on the solar energy storage performance is further discussed and analyzed. The experimental results prove that PCM-STEG coupling system can output more electric energy than pure STEG system because PCM can decline the heat transfer and storage thermal energy to further generate the electric energy through thermal-to-electric conversion when the light is removed. The increase of PCM thickness can reduce the heat transfer and enhance thermal storage, and then the power generation performance of PCM-STEG coupling system can be improved. As the increase of light intensity, the output electric energy of the coupling system rises accordingly, and the maximum amount of electrical energy can reach by 113.85 J at 1.6 W/cm2. The study of the PCM-STEG coupling system has certain reference for the development of solar energy storage and application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title="solar energy">solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20thermoelectric%20generator" title=" solar thermoelectric generator"> solar thermoelectric generator</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20change%20materials" title=" phase change materials"> phase change materials</a>, <a href="https://publications.waset.org/abstracts/search?q=solar-to-electric%20energy" title=" solar-to-electric energy"> solar-to-electric energy</a>, <a href="https://publications.waset.org/abstracts/search?q=DM%2FMWCNT" title=" DM/MWCNT"> DM/MWCNT</a> </p> <a href="https://publications.waset.org/abstracts/177662/investigation-on-solar-thermoelectric-generator-using-d-mannitolmulti-walled-carbon-nanotubes-composite-phase-change-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177662.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">72</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">1826</span> A Study on Analysis of Magnetic Field in Induction Generator for Small Francis Turbine Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Kwan%20Choi">Young-Kwan Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Han-Sang%20Jeong"> Han-Sang Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeon-Ho%20Ok"> Yeon-Ho Ok</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Ho%20Choi"> Jae-Ho Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to verify validity of design by testing output of induction generator through finite element analysis before manufacture of induction generator designed.

The TEG module consists of a thermoelectric generator, an elliptical pin-fin heat sink, and a cold plate for water cooling. In the chimney, the temperature of flue gases is 450-650K. Therefore, the effects of convection and radiation heat transfer are considered. Although the TEG hot-side temperature and thus the electric power output can be increased by inserting an elliptical pin-fin heat sink into the chimney tunnel to increase the heat transfer area, the pin fin heat sink would cause extra pumping power at the same time. The main purpose of this study is to analyze the effects of geometrical parameters on the electric power output and chimney pressure drop characteristics. In addition, the effects of different operating conditions, including various inlet velocities (Vin = 1, 3, 5 m/s) and inlet temperatures (Tgas = 450, 550, 650K) are discussed in detail. The predicted numerical data for the power vs. current (P-I) curve are in good agreement (within 11%) with the experimental data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermoelectric%20generator" title="thermoelectric generator">thermoelectric generator</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20heat%20recovery" title=" waste heat recovery"> waste heat recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=pin-fin%20heat%20sink" title=" pin-fin heat sink"> pin-fin heat sink</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20and%20numerical%20analysis" title=" experimental and numerical analysis"> experimental and numerical analysis</a> </p> <a href="https://publications.waset.org/abstracts/13661/experimental-and-numerical-analysis-of-built-in-thermoelectric-generator-modules-with-elliptical-pin-fin-heat-sink" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13661.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">382</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">1822</span> Stability Analysis of a Low Power Wind Turbine for the Simultaneous Generation of Energy through Two Electric Generators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Icaza">Daniel Icaza</a>, <a href="https://publications.waset.org/abstracts/search?q=Federico%20C%C3%B3rdova"> Federico Córdova</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiristian%20Castro"> Chiristian Castro</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Icaza"> Fernando Icaza</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Portoviejo"> Juan Portoviejo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, the mathematical model is presented, and simulations were carried out using specialized software such as MATLAB before the construction of a 900-W wind turbine.

Fault resistance is a critical parameter of electric power systems operation due to its stochastic nature.

Kordi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wireless electric field sensors are in high demand in the number of applications that requires measuring electric field such as investigations of high power systems and testing the high voltage apparatus. Passive wireless electric field sensors are most desired since they do not require a source of power and are interrogated wirelessly. A passive wireless electric field sensor has been designed and fabricated by our research group. In the wireless interrogation system of the sensor, a wireless radio frequency impulse generator needs to be employed. A compact wireless impulse generator composed of an integrated resonant switched oscillator (SWO) and a pulse-radiating antenna has been designed and fabricated in this research. The fundamental of Switched Oscillators was introduced by C.E.Baum. A Switched Oscillator consists of a low impedance transmission line charged by a DC source, through large impedance at desired frequencies and terminated to a high impedance antenna at one end and a fast closing switch at the other end. Once the line is charged, the switch will close and short-circuit the transmission line. Therefore, a fast transient wave will be generated and travels along the transmission line. Because of the mismatch between the antenna and the transmission line, only a part of fast transient wave will be radiated, and a portion of the fast-transient wave will reflect back. At the other end of the transmission line, there is a closed switch. Consequently, a second reflection with a reversed sign will propagate towards the antenna and the wave continues back and forth. hence, at the terminal of the antenna, there will be a series of positive and negative pulses with descending amplitude. In this research a single ended quarter wavelength Switched Oscillator has been designed and simulated at 800MHz. The simulation results show that the designed Switched Oscillator generates pulses with decreasing amplitude at the frequency of 800MHz with the maximum amplitude of 10V and bandwidth of about 10MHz at the antenna end. The switched oscillator has been fabricated using a 6cm long coaxial cable transmission line which is charged by a DC source and an 8cm monopole antenna as the pulse radiating antenna. A 90V gas discharge switch has been employed as the fast closing switch. The Switched oscillator sends a series of pulses with decreasing amplitude at the frequency of 790MHz with the maximum amplitude of 0.3V in the distance of 30 cm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20field%20measurement" title="electric field measurement">electric field measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=impulse%20radiating%20antenna" title=" impulse radiating antenna"> impulse radiating antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=switched%20oscillator" title=" switched oscillator"> switched oscillator</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20impulse%20generator" title=" wireless impulse generator"> wireless impulse generator</a> </p> <a href="https://publications.waset.org/abstracts/105070/wireless-integrated-switched-oscillator-impulse-generator-with-application-in-wireless-passive-electric-field-sensors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105070.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">181</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">1818</span> An Experimental Study on the Temperature Reduction of Exhaust Gas at a Snorkeling of Submarine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seok-Tae%20Yoon">Seok-Tae Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Yeong%20Choi"> Jae-Yeong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gyu-Mok%20Jeon"> Gyu-Mok Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Jin%20Cho"> Yong-Jin Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Chun%20Park"> Jong-Chun Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conventional submarines obtain propulsive force by using an electric propulsion system consisting of a diesel generator, battery, motor, and propeller. In the underwater, the submarine uses the electric power stored in the battery. After that, when a certain amount of electric power is consumed, the submarine floats near the sea water surface and recharges the electric power by using the diesel generator. The voyage carried out while charging the power is called a snorkel, and the high-temperature exhaust gas from the diesel generator forms a heat distribution on the sea water surface. The heat distribution is detected by weapon system equipped with thermo-detector and that is the main cause of reducing the survivability of the submarine. In this paper, an experimental study was carried out to establish optimal operating conditions of a submarine for reduction of infrared signature radiated from the sea water surface. For this, a hot gas generating system and a round acrylic water tank with adjustable water level were made. The control variables of the experiment were set as the mass flow rate, the temperature difference between the water and the hot gas in the water tank, and the water level difference between the air outlet and the water surface. The experimental instrumentation used a thermocouple of T-type to measure the released air temperature on the surface of the water, and a thermography system to measure the thermal energy distribution on the water surface. As a result of the experiment study, we analyzed the correlation between the final released temperature of the exhaust pipe exit in a submarine and the depth of the snorkel, and presented reasonable operating conditions for the infrared signature reduction of submarine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experiment%20study" title="experiment study">experiment study</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20rate" title=" flow rate"> flow rate</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20signature" title=" infrared signature"> infrared signature</a>, <a href="https://publications.waset.org/abstracts/search?q=snorkeling" title=" snorkeling"> snorkeling</a>, <a href="https://publications.waset.org/abstracts/search?q=thermography" title=" thermography"> thermography</a> </p> <a href="https://publications.waset.org/abstracts/87195/an-experimental-study-on-the-temperature-reduction-of-exhaust-gas-at-a-snorkeling-of-submarine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87195.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">352</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">1817</span> Development and Validation of Cylindrical Linear Oscillating Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sungin%20Jeong">Sungin Jeong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a linear oscillating generator of cylindrical type for hybrid electric vehicle application. The focus of the study is the suggestion of the optimal model and the design rule of the cylindrical linear oscillating generator with permanent magnet in the back-iron translator. The cylindrical topology is achieved using equivalent magnetic circuit considering leakage elements as initial modeling. This topology with permanent magnet in the back-iron translator is described by number of phases and displacement of stroke. For more accurate analysis of an oscillating machine, it will be compared by moving just one-pole pitch forward and backward the thrust of single-phase system and three-phase system. Through the analysis and comparison, a single-phase system of cylindrical topology as the optimal topology is selected. Finally, the detailed design of the optimal topology takes the magnetic saturation effects into account by finite element analysis. Besides, the losses are examined to obtain more accurate results; copper loss in the conductors of machine windings, eddy-current loss of permanent magnet, and iron-loss of specific material of electrical steel. The considerations of thermal performances and mechanical robustness are essential, because they have an effect on the entire efficiency and the insulations of the machine due to the losses of the high temperature generated in each region of the generator. Besides electric machine with linear oscillating movement requires a support system that can resist dynamic forces and mechanical masses. As a result, the fatigue analysis of shaft is achieved by the kinetic equations. Also, the thermal characteristics are analyzed by the operating frequency in each region. The results of this study will give a very important design rule in the design of linear oscillating machines. It enables us to more accurate machine design and more accurate prediction of machine performances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equivalent%20magnetic%20circuit" title="equivalent magnetic circuit">equivalent magnetic circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</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=linear%20oscillating%20generator" title=" linear oscillating generator"> linear oscillating generator</a> </p> <a href="https://publications.waset.org/abstracts/72504/development-and-validation-of-cylindrical-linear-oscillating-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72504.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">195</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">1816</span> Study of Linear Generator for Vibration Energy Harvesting of Frequency more than 50Hz</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seong-Jin%20Cho">Seong-Jin Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Ho%20Kim"> Jin Ho Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy harvesting is the technology which gathers and converts external energies such as light, vibration and heat which are disposed into reusable electrical energy and uses such electrical energy. The vibration energy harvesting is very interesting technology because it produces very high density of energy and unaffected by the climate. Vibration energy can be harvested by the electrostatic, electromagnetic and piezoelectric systems. The electrostatic system has low energy conversion efficiency, and the piezoelectric system is expensive and needs the frequent maintenance because it is made of piezoelectric ceramic. On the other hand, the electromagnetic system has a long life time and high harvesting efficiency, and it is relatively cheap. The electromagnetic harvesting system includes the linear generator and the rotary-type generator. The rotary-type generators require the additional mechanical conversion device if it uses linear motion of vibration. But, the linear generator uses directly linear motion of vibration without a mechanical conversion device, and it has uncomplicated structure and light weight compared with the rotary-type generator. Therefore, the linear electromagnetic generator can be useful in using vibration energy harvesting. The pole transformer systems need electricity sensor system for sending voltage and power information to administrator. Therefore, the battery is essential, and its regular maintenance of replacement is required. In case of the transformer of high location in mountainous areas, the person can’t easily access it resulting in high maintenance cost. To overcome these problems, we designed and developed the linear electromagnetic generator which can replace battery in electricity sensor system for sending voltage and power information of the pole transformer. And, it uses vibration energy of frequency more than 50 Hz by the pole transformer. In order to analyze the electromagnetic characteristics of small linear electric generator, a commercial electromagnetic finite element analysis program "MAXWELL" was used. Then, through the actual production and experiment of linear generator, we confirmed output power of linear generator. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20harvesting" title="energy harvesting">energy harvesting</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency" title=" frequency"> frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20generator" title=" linear generator"> linear generator</a>, <a href="https://publications.waset.org/abstracts/search?q=experiment" title=" experiment"> experiment</a> </p> <a href="https://publications.waset.org/abstracts/56580/study-of-linear-generator-for-vibration-energy-harvesting-of-frequency-more-than-50hz" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56580.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">259</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">1815</span> Design and Fabrication of Micro-Bubble Oxygenator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chiang-Ho%20Cheng">Chiang-Ho Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=An-Shik%20Yang"> An-Shik Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong-Yih%20Cheng"> Hong-Yih Cheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper applies the MEMS technology to design and fabricate a micro-bubble generator by a piezoelectric actuator.

Most of the current commercialized thermal, including geothermal, power-generation technologies convert thermal energy to electric energy indirectly, that is, making mechanical work before producing electricity. Technology using thermoelectric generator (TEG), however, can directly transform thermal energy into electricity by using Seebeck effect. TEG technology has many advantages such as compactness, quietness, and reliability because there are no moving parts. One of the big disadvantages of TEGs is the low efficiency from thermal to electric energy. For this reason, we redesigned and modified our previous 1 KW (at a temperature difference of around 120 °C) TEG system. The efficiency of the system was improved significantly, about 20% greater. Laboratory experiments have been conducted to measure the output power, including both open and net power, at different conditions: different modes of connections between TEG modules, different mechanical structures, different temperature differences between hot and cold sides. The cost of the TEG power generator has been reduced further because of the increased efficiency and is lower than that of photovoltaics (PV) in terms of equivalent energy generated. The TEG apparatus has been pilot tested and the data will be presented. This kind of TEG power system can be applied in many thermal and geothermal sites with low temperature resources, including oil fields where fossil and geothermal energies are co-produced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TEG" title="TEG">TEG</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20power%20generation" title=" direct power generation"> direct power generation</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoelectric%20effect" title=" thermoelectric effect"> thermoelectric effect</a> </p> <a href="https://publications.waset.org/abstracts/59177/enhanced-efficiency-of-thermoelectric-generator-by-optimizing-mechanical-and-electrical-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59177.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">242</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">1813</span> Permanent Magnet Generator – One Phase Regime Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pawel%20Pistelok">Pawel Pistelok</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article presents the concept of an electromagnetic circuit of a 3-phase surface-mounted permanent magnet generator designed for a single phase operation.

The second version of generator is very similar, i.e. three winding phases are connected in series and one phase load is powered by generator, but in this version the voltages generated in each of winding phases have exactly the same rms values (the same number of turns in each of phases). The time waveforms of voltages, currents and electromagnetic torques in the airgaps of two machine versions for rated power are shown. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet%20generator" title="permanent magnet generator">permanent magnet generator</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnets" title=" permanent magnets"> permanent magnets</a>, <a href="https://publications.waset.org/abstracts/search?q=synchronous%20generator" title=" synchronous generator"> synchronous generator</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration" title=" vibration"> vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=course%20of%20torque" title=" course of torque"> course of torque</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20phase%20work" title=" single phase work"> single phase work</a>, <a href="https://publications.waset.org/abstracts/search?q=unsymmetrical%20operation%20point" title=" unsymmetrical operation point"> unsymmetrical operation point</a>, <a href="https://publications.waset.org/abstracts/search?q=serial%20connection%20of%20winding%20phase" title=" serial connection of winding phase"> serial connection of winding phase</a> </p> <a href="https://publications.waset.org/abstracts/29809/permanent-magnet-generator-one-phase-regime-operation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29809.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">695</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">1812</span> Internet of Things-Based Electric Vehicle Charging Notification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nagarjuna%20Pitty">Nagarjuna Pitty</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is believed invention “Advanced Method and Process Quick Electric Vehicle Charging” is an Electric Vehicles (EVs) are quickly turning into the heralds of vehicle innovation.

The share of electric vehicles in the sale of new cars increases every year. However, their performance and, above all, range cannot be today successfully compared to those of cars with a traditional internal combustion engine. Battery recharging lasts hours, which can be hardly accepted due to the time needed to refill a fuel tank. Therefore, the ways to reduce the adverse features of cars equipped with electric motors only are searched for. One of the methods is a combination of an electric engine as a main source of power and a small internal combustion engine as an electricity generator. This type of drive enables an electric vehicle to achieve a radically increased range and low emissions of toxic substances. For several years, the leading automotive manufacturers like the Mazda and the Audi together with the best companies in the automotive industry, e.g., AVL have developed some electric drive systems capable of recharging themselves while driving, known as a range extender. An electricity generator is powered by a Wankel engine that has seemed to pass into history. This low weight and small engine with a rotating piston and a very low vibration level turned out to be an excellent source in such applications. Its operation as an energy source for a generator almost entirely eliminates its disadvantages like high fuel consumption, high emission of toxic substances, or short lifetime typical of its traditional application. The operation of the engine at a constant rotational speed enables a significant increase in its lifetime, and its small external dimensions enable us to make compact modules to drive even small urban cars like the Audi A1 or the Mazda 2. The algorithm to maintain a constant speed was investigated on the engine dynamometer with an eddy current brake and the necessary measuring apparatus. The research object was the Aixro XR50 rotary engine with the electronic power supply developed at the Lublin University of Technology. The load torque of the engine was altered during the research by means of the eddy current brake capable of giving any number of load cycles. The parameters recorded included speed and torque as well as a position of a throttle in an inlet system. Increasing and decreasing load did not significantly change engine speed, which means that control algorithm parameters are correctly selected. This work has been financed by the Polish Ministry of Science and Higher Education. <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=power%20generator" title=" power generator"> power generator</a>, <a href="https://publications.waset.org/abstracts/search?q=range%20extender" title=" range extender"> range extender</a>, <a href="https://publications.waset.org/abstracts/search?q=Wankel%20engine" title=" Wankel engine"> Wankel engine</a> </p> <a href="https://publications.waset.org/abstracts/81482/investigating-the-algorithm-to-maintain-a-constant-speed-in-the-wankel-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81482.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">157</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">1810</span> Development of an Analytical Model for a Synchronous Permanent Magnet Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Sahbani">T.

The edge space of G, denoted by ε(G), is a vector space over the field Z2. The elements of ε(G) are all the subsets of E(G). Vector addition is defined as X+Y = X Δ Y, the symmetric difference of sets X and Y, for X, Y ∈ ε(G). Scalar multiplication is defined as 1.X =X and 0.X = Ø for X ∈ ε(G). The set S ⊆ ε(G) is called a generating set if every element ε(G) is a linear combination of the elements of S. For a non-empty set X ∈ ε(G), the smallest subgraph with edge set X is called edge-induced subgraph of G, denoted by G[X].

Joy Thomas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Increasing the shelf life and improving the quality are important objectives for the success of packaged liquid food industry. One of the methods by which this can be achieved is by deactivating the micro-organisms present in the liquid food through pasteurization. Pasteurization is done by heating, but some serious disadvantages such as the reduction in food quality, flavour, taste, colour, etc. were observed because of heat treatment, which leads to the development of newer methods instead of pasteurization such as treatment using UV radiation, high pressure, nuclear irradiation, pulsed electric field, etc. In recent years the use of the pulsed electric field (PEF) for inactivation of the microbial content in the food is gaining popularity. PEF uses a very high electric field for a short time for the inactivation of microorganisms, for which we require a high voltage pulsed power source. Pulsed power sources used for PEF treatments are usually in the range of 5kV to 50kV. Different pulse shapes are used, such as exponentially decaying and square wave pulses. Exponentially decaying pulses are generated by high power switches with only turn-on capacity and, therefore, discharge the total energy stored in the capacitor bank. These pulses have a sudden onset and, therefore, a high rate of rising but have a very slow decay, which yields extra heat, which is ineffective in microbial inactivation. Square pulses can be produced by an incomplete discharge of a capacitor with the help of a switch having both on/off control or by using a pulse forming network. In this work, a pulsed power-based system is designed with the help of high voltage capacitors and solid-state switches (IGBT) for the inactivation of pathogenic micro-organism in liquid food such as fruit juices. The high voltage generator is based on the Marx generator topology, which can produce variable amplitude, frequency, and pulse width according to the requirements. Liquid food is treated in a chamber where pulsed electric field is produced between stainless steel electrodes using the pulsed output voltage of the supply. Preliminary bacterial inactivation tests were performed by subjecting orange juice inoculated with Escherichia Coli bacteria. With the help of the developed pulsed power source and the chamber, the inoculated orange has been PEF treated. The voltage was varied to get a peak electric field up to 15kV/cm. For a total treatment time of 200µs, a 30% reduction in the bacterial count has been observed. The detailed results and analysis will be presented in the final paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Escherichia%20coli%20bacteria" title="Escherichia coli bacteria">Escherichia coli bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20voltage%20generator" title=" high voltage generator"> high voltage generator</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20inactivation" title=" microbial inactivation"> microbial inactivation</a>, <a href="https://publications.waset.org/abstracts/search?q=pulsed%20electric%20field" title=" pulsed electric field"> pulsed electric field</a>, <a href="https://publications.waset.org/abstracts/search?q=pulsed%20forming%20line" title=" pulsed forming line"> pulsed forming line</a>, <a href="https://publications.waset.org/abstracts/search?q=solid-state%20switch" title=" solid-state switch"> solid-state switch</a> </p> <a href="https://publications.waset.org/abstracts/133798/liquid-food-sterilization-using-pulsed-electric-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133798.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">184</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">1806</span> Temperature Rises Characteristics of Distinct Double-Sided Flat Permanent Magnet Linear Generator for Free Piston Engines for Hybrid Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Rahama%20Adam%20Hamid">Ismail Rahama Adam Hamid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the development of a thermal model for a flat, double-sided linear generator designed for use in free-piston engines. The study conducted in this paper examines the influence of temperature on the performance of the permeant magnet linear generator, an integral and pivotal component within the system. This research places particular emphasis on the Neodymium Iron Boron (NdFeB) permanent magnet, which serves as a source of magnetic field for the linear generator. In this study, an internal combustion engine that tends to produce heat is connected to a generator. Considering the temperatures rise from both the combustion process and the thermal contributions of current-carrying conductors and frictional forces. Utilizing Computational Fluid Dynamics (CFD) method, a thermal model of the (NdFeB) magnet within the linear generator is constructed and analyzed.
