tracking continuously the maximum power point(MPP) which depends on panels temperature and on irradiance conditions. The main drawback of P&O is that, the operating point oscillates around the MPP giving rise to the waste of some amount of available energy; moreover, it is well known that the P&O algorithm can be confused during those time intervals characterized by rapidly changing atmospheric conditions. In this paper, it is shown that in order to limit the negative effects associated to the above drawbacks, the P&O MPPT parameters must be customized to the dynamic behavior of the specific converter adopted. A theoretical analysis allowing the optimal choice of such initial set parameters is also carried out. The fast convergence of the proposal is proven. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=P%26O" title="P&O">P&O</a>, <a href="https://publications.waset.org/abstracts/search?q=Taylor%E2%80%99s%20series" title=" Taylor’s series"> Taylor’s series</a>, <a href="https://publications.waset.org/abstracts/search?q=MPPT" title=" MPPT"> MPPT</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20panel" title=" photovoltaic panel "> photovoltaic panel </a> </p> <a href="https://publications.waset.org/abstracts/21985/improvement-perturb-and-observe-for-a-fast-response-mppt-applied-to-photovoltaic-panel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21985.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">587</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">88</span> Thermoelectrical Properties of Cs Doped BiCuSeO as Promising Oxide Materials for Thermoelectric Energy Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdenour%20Achour">Abdenour Achour</a>, <a href="https://publications.waset.org/abstracts/search?q=Kan%20Chen"> Kan Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mike%20Reece"> Mike Reece</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhaorong%20Huang"> Zhaorong Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Here we report the synthesis of pure and cost effective of BiCuSeO by a flux method in air, and the enhancement of the thermoelectric performance by Cs doping. The comparison between our synthesis and the usual vacuum furnace method has been studied for the pristine oxyselenides BiCuSeO. We report for very high Seebeck coefficients up to 516 μV K⁻¹ at room temperature with the electrical conductivity of 5.20 S cm⁻¹ which lead to a high power factor of 140 µWm⁻¹K⁻². We also report at the high temperatures the lowest thermal conductivity value of 0.42 µWm⁻¹K⁻¹. Upon doping with Cs, enhanced electrical conductivity coupled with a moderate Seebeck coefficient lead to a power factor of 338 µWm⁻¹K⁻² at 682 K. Moreover, it shows a very low thermal conductivity in the temperature range of 300 to 682 K (0.75 to 0.35 Wm⁻¹K⁻¹). By optimizing the power factor and reducing the thermal conductivity, this results in a high ZT of ~ 0.66 at 682 K for Bi0.995Cs0.005CuSeO. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BiCuSeO" title="BiCuSeO">BiCuSeO</a>, <a href="https://publications.waset.org/abstracts/search?q=Cs%20doping" title=" Cs doping"> Cs doping</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoelectric" title=" thermoelectric"> thermoelectric</a>, <a href="https://publications.waset.org/abstracts/search?q=oxyselenide" title=" oxyselenide"> oxyselenide</a> </p> <a href="https://publications.waset.org/abstracts/56690/thermoelectrical-properties-of-cs-doped-bicuseo-as-promising-oxide-materials-for-thermoelectric-energy-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56690.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">300</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">87</span> Design and Performance Analysis of Advanced B-Spline Algorithm for Image Resolution Enhancement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Z.%20Kurian">M.

The proposed Advanced B-Spline method generates a high-resolution (HR) image from single LR image and tries to retain the higher frequency components such as edges in the image. This method uses B-Spline technique and Crispening. This work is evaluated qualitatively and quantitatively using Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR). The method is also suitable for real-time applications. Different combinations of decimation and super-resolution algorithms in the presence of different noise and noise factors are tested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=advanced%20b-spline" title="advanced b-spline">advanced b-spline</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20super-resolution" title=" image super-resolution"> image super-resolution</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20square%20error%20%28MSE%29" title=" mean square error (MSE)"> mean square error (MSE)</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20signal%20to%20noise%20ratio%20%28PSNR%29" title=" peak signal to noise ratio (PSNR)"> peak signal to noise ratio (PSNR)</a>, <a href="https://publications.waset.org/abstracts/search?q=resolution%20down%20converter" title=" resolution down converter"> resolution down converter</a> </p> <a href="https://publications.waset.org/abstracts/59499/design-and-performance-analysis-of-advanced-b-spline-algorithm-for-image-resolution-enhancement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59499.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">399</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">86</span> Low Cost Surface Electromyographic Signal Amplifier Based on Arduino Microcontroller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Igor%20Luiz%20Bernardes%20de%20Moura">Igor Luiz Bernardes de Moura</a>, <a href="https://publications.waset.org/abstracts/search?q=Luan%20Carlos%20de%20Sena%20Monteiro%20Ozelim"> Luan Carlos de Sena Monteiro Ozelim</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabiano%20Araujo%20Soares"> Fabiano Araujo Soares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of a low cost acquisition system of S-EMG signals which are reliable, comfortable for the user and with high mobility shows to be a relevant proposition in modern biomedical engineering scenario.

The proposed model uses single-phase phase locked loop (PLL) to synchronize SPI with the grid and performs MPC control in a dq reference frame. SPI model consists of boost converter (BC), maximum power point tracking (MPPT) control, and a full bridge (FB) voltage source inverter (VSI). No PI regulators to tune and carrier and modulating waves are required to produce switching sequence. Instead, the operational model of VSI is used to synthesize sinusoidal current and track the reference. Model is validated using a three kW PV system at the input of UI-SPI in Matlab/Simulink. Implementation and results demonstrate simplicity and accuracy, as well as reliability of the model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phase%20locked%20loop" title="phase locked loop">phase locked loop</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20source%20inverter" title=" voltage source inverter"> voltage source inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20phase%20inverter" title=" single phase inverter"> single phase inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20predictive%20control" title=" model predictive control"> model predictive control</a>, <a href="https://publications.waset.org/abstracts/search?q=Matlab%2FSimulink" title=" Matlab/Simulink"> Matlab/Simulink</a> </p> <a href="https://publications.waset.org/abstracts/16006/mpc-of-single-phase-inverter-for-pv-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16006.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">532</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">83</span> Design of Wide-Range Variable Fractional-Delay FIR Digital Filters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jong-Jy%20Shyu">Jong-Jy Shyu</a>, <a href="https://publications.waset.org/abstracts/search?q=Soo-Chang%20Pei"> Soo-Chang Pei</a>, <a href="https://publications.waset.org/abstracts/search?q=Yun-Da%20Huang"> Yun-Da Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, design of wide-range variable fractional-delay (WR-VFD) finite impulse response (FIR) digital filters is proposed. With respect to the conventional VFD filter which is designed such that its delay is adjustable within one unit, the proposed VFD FIR filter is designed such that its delay can be tunable within a wider range. By the traces of coefficients of the fractional-delay FIR filter, it is found that the conventional method of polynomial substitution for filter coefficients no longer satisfies the design demand, and the circuits perform the sinc function (sinc converter) are added to overcome this problem.

This would assist in harnessing more of the available solar energy. The practical setup consists of a PV panel that is set to an orientation angle of 0º N, with corresponding tilt angles.

The decimation filters work twofold; they decimate the sampling rate by a factor of OSR (oversampling rate) and they remove the out band quantization noise resulting in an increase in resolution. The speed, area and power consumption of oversampled converter are governed largely by decimation filters in sigma-delta A/D converters. The scope of the work is to design a decimation filter for sigma-delta ADC and simulation using MATLAB. The decimation filter structure is based on cascaded-integrated comb (CIC) filter. A second decimation filter is using CIC for large rate change and cascaded FIR filters, for small rate changes, to improve the frequency response.

Because photovoltaic generates power in low voltage, first, generated power should increase. Usually, distributed generation injects their power to AC-Grid, hence after voltage increasing an inverter is needed to convert DC power to AC power. This results in utilization two series converter that grows cost, complexity, and low efficiency. In this paper a single stage inverter is utilized to boost and invert in one stage. Control of this scheme is easier, and its initial cost decreases comparing to conventional double stage inverters. A simple control scheme is used to control active power as well as minimum total harmonic distortion (THD) in injected current. Simulations in MATLAB demonstrate better outputs comparing with conventional approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maximum%20power%20point%20tracking" title="maximum power point tracking">maximum power point tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=boost%20inverter" title=" boost inverter"> boost inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20strategy" title=" control strategy"> control strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=three%20phase%20inverter" title=" three phase inverter"> three phase inverter</a> </p> <a href="https://publications.waset.org/abstracts/47543/control-scheme-for-single-stage-boost-inverter-for-grid-connected-photovoltaic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47543.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">78</span> A Model Predictive Control Based Virtual Active Power Filter Using V2G Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Zolfaghari">Mahdi Zolfaghari</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Hossein%20Hosseinian"> Seyed Hossein Hosseinian</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Askarian%20Abyaneh"> Hossein Askarian Abyaneh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Abedi"> Mehrdad Abedi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a virtual active power filter (VAPF) using vehicle to grid (V2G) technology to maintain power quality requirements.

However, the output power induced in the photovoltaic modules is influenced by an intensity of solar cell radiation, temperature of the solar cells and so on. Therefore, to maximize the efficiency of the photovoltaic system, it is necessary to track the maximum power point of the PV array, for this Maximum Power Point Tracking (MPPT) technique is used. Some MPPT techniques are available in that perturbation and observation (P&O) and Fuzzy logic controller (FLC). The fuzzy control method has been compared with perturb and observe (P&O) method as one of the most widely conventional method used in this area. Both techniques have been analyzed and simulated.

Furthermore, MFC can be used directly as biosensor to analyse parameters like pH and temperature or arranged in form of cluster devices in order to use as small power plant. An MFC is a bioreactor that converts energy stored in chemical bonds of organic matter into electrical energy, through a series of reactions catalysed by microorganisms. We have developed a lab-scale terrestrial microbial fuel cell (TMFC), based on soil that acts as source of bacteria and flow of nutrient and a lab-scale waste water microbial fuel cell (WWMFC), where waste water acts as flow of nutrient and bacteria. We performed large series of tests to exploit the capability as biosensor. The pH value has strong influence on the open circuit voltage (OCV) delivered from TMFCs. We analyzed three condition: test A and B were filled with same soil but changing pH from 6 to 6.63, test C was prepared using a different soil with a pH value of 6.3. Experimental results clearly show how with higher pH value a higher OCV was produced; indeed reactors are influenced by different values of pH which increases the voltage in case of a higher pH value until the best pH value of 7 is achieved. The influence of pH on OCV of lab-scales WWMFC was analyzed at pH value of 6.5, 7, 7.2, 7.5 and 8. WWMFCs are influenced from temperature more than TMFCs. We tested the power performance of WWMFCs considering four imposed values of ambient temperature. Results show how power performance increase proportionally with higher temperature values, doubling the output power from 20° to 40°. The best value of power produced from our lab-scale TMFC was equal to 310 μW using peaty soil, at 1KΩ, corresponding to a current of 0.5 mA. A TMFC can supply proper energy to low power devices of a WSN by means of the design of three stages scheme of an energy management system, which adapts voltage level of TMFC to those required by a WSN node, as 3.3V. Using a commercial DC/DC boost converter, that needs an input voltage of 700 mV, the current source of 0.5 mA, charges a capacitor of 6.8 mF until it will have accumulated an amount of charge equal to 700 mV in a time of 10 s. The output stage includes an output switch that close the circuit after a time of 10s + 1.5ms because the converter can boost the voltage from 0.7V to 3.3V in 1.5 ms. Furthermore, we tested in form of clusters connected in series up to 20 WWMFCs, we have obtained a high voltage value as output, around 10V, but low current value. MFC can be considered a suitable clean energy source to be used to supply low power devices as a WSN node or to be used directly as biosensor. <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=low%20power%20electronics" title=" low power electronics"> low power electronics</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20fuel%20cell" title=" microbial fuel cell"> microbial fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=terrestrial%20microbial%20fuel%20cell" title=" terrestrial microbial fuel cell"> terrestrial microbial fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=waste-water%20microbial%20fuel%20cell" title=" waste-water microbial fuel cell"> waste-water microbial fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20network" title=" wireless sensor network"> wireless sensor network</a> </p> <a href="https://publications.waset.org/abstracts/77255/microbial-fuel-cells-performance-and-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77255.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">207</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">72</span> Providing Additional Advantages for STATCOM in Power Systems by Integration of Energy Storage Device</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Sedaghati">Reza Sedaghati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of Flexible AC Transmission System (FACTS) devices in a power system can potentially overcome limitations of the present mechanically controlled transmission system. Also, the advance of technology makes possible to include new energy storage devices in the electrical power system. The integration of Superconducting Magnetic Energy Storage (SMES) into Static Synchronous Compensator (STATCOM) can lead to increase their flexibility in improvement of power system dynamic behaviour by exchanging both active and reactive powers with power grids.

This converter topology is evaluated on the basis of performance and its salient features like simplicity, low cost and high performance are discussed to analyze its applicability. The proposed control strategy is bridgeless, transformer-less and output current sensor-less and consists of only two Bi-directional IGBTs and two diodes. The voltage regulation is achieved by a simple voltage divider to communicate to a controller to control the duty cycles of PWM. A control technique and operational procedure are also developed, both theoretically and experimentally. The experimental results clearly verify the theoretical analysis from the prototype connected to grid unity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Active%20Rectifier%20%28AC-DC%29" title="Active Rectifier (AC-DC)">Active Rectifier (AC-DC)</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20factor" title=" power factor"> power factor</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20phase" title=" single phase"> single phase</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20regulation" title=" voltage regulation"> voltage regulation</a> </p> <a href="https://publications.waset.org/abstracts/3045/a-continuous-switching-technique-for-a-single-phase-bridgeless-and-transformer-less-active-rectifier-with-high-power-factor-and-voltage-stabilization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3045.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">580</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">70</span> Implementation and Design of Fuzzy Controller for High Performance Dc-Dc Boost Converters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Mansouri">A.

Design of PI controllers is based on temporal response of closed-loop converters, while fuzzy controllers design is based on heuristic knowledge of boost converters. Linear controller implementation is quite straightforward relying on mathematical models, while fuzzy controller implementation employs one or more artificial intelligences techniques. Comparison between these boost controllers is made in design aspect. Experimental results show that the proposed fuzzy controller system is robust against input voltage and load resistance changing and in respect of start-up transient. Results indicate that fuzzy controller can achieve best control performance concerning faster transient response, steady-state response good stability and accuracy under different operating conditions.

Ripple Carry Adder (RCA) used in parallel addition but propagation delay time is large. RCA replaced with Carry Select Adder (CSLA) to reduce propagation delay time. CSLA design with dual RCA considering carry = ‘0’ and carry = ‘1’, so it is not an area efficient adder. To make area efficient, modified CSLA is designed with single RCA considering carry = ‘0’ and another RCA considering carry = ‘1’ replaced with Binary to Excess 1 Converter (BEC).

This paper presents the operation and vector control of a Doubly-fed Induction Generator (DFIG) system where the stator is connected directly to a stiff grid and the rotor is connected to the grid through bidirectional back-to-back AC-DC-AC converter.

Fault detection, location, and isolation, as well as maintaining fault ride-through (FRT), are major challenges to MMC reliability and power supply sustainability. Different papers have been reviewed to seek the best MMC configuration with fault capability. DC faults are the most common fault, while the probability that AC fault occurs in a modular multilevel converter (MCC) is low; though, AC faults consequence are severe. This paper reviews several MMC topologies and modulation techniques in tackling faults. These fault control strategies are compared based on cost, complexity, controllability, and power loss. A meshed network of half-bridge (HB) MMC topology was optimal in rendering fault ride through than any other MMC topologies but only when combined with DC circuit breakers (CBS), AC CBS, and fault current limiters (FCL). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MMC-HVDC" title="MMC-HVDC">MMC-HVDC</a>, <a href="https://publications.waset.org/abstracts/search?q=DC%20faults" title=" DC faults"> DC faults</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20current%20limiters" title=" fault current limiters"> fault current limiters</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20scheme" title=" control scheme"> control scheme</a> </p> <a href="https://publications.waset.org/abstracts/113483/a-review-of-hvdc-modular-multilevel-converters-subjected-to-dc-and-ac-faults" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113483.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">140</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">65</span> A Study on Unidirectional Analog Output Voltage Inverter for Capacitive Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sun-Ki%20Hong">Sun-Ki Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Nam-HeeByeon"> Nam-HeeByeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung-Seop%20Lee"> Jung-Seop Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Sam%20Kang"> Tae-Sam Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For Common R or R-L load to apply arbitrary voltage, the bridge traditional inverters don’t have any difficulties by PWM method. However for driving some piezoelectric actuator, arbitrary voltage not a pulse but a steady voltage should be applied. Piezoelectric load is considered as R-C load and its voltage does not decrease even though the applied voltage decreases. Therefore it needs some special inverter with circuit that can discharge the capacitive energy. Especially for unidirectional arbitrary voltage driving like as sine wave, it becomes more difficult problem. In this paper, a charge and discharge circuit for unidirectional arbitrary voltage driving for piezoelectric actuator is proposed. The circuit has charging and discharging switches for increasing and decreasing output voltage. With the proposed simple circuit, the load voltage can have any unidirectional level with tens of bandwidth because the load voltage can be adjusted by switching the charging and discharging switch appropriately. The appropriateness is proved from the simulation of the proposed circuit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC-DC%20converter" title="DC-DC converter">DC-DC converter</a>, <a href="https://publications.waset.org/abstracts/search?q=analog%20output%20voltage" title=" analog output voltage"> analog output voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=sinusoidal%20drive" title=" sinusoidal drive"> sinusoidal drive</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoelectric%20load" title=" piezoelectric load"> piezoelectric load</a>, <a href="https://publications.waset.org/abstracts/search?q=discharging%20circuit" title=" discharging circuit "> discharging circuit </a> </p> <a href="https://publications.waset.org/abstracts/8464/a-study-on-unidirectional-analog-output-voltage-inverter-for-capacitive-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8464.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">380</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">64</span> The Evaluation of Electricity Generation and Consumption from Solar Generator: A Case Study at Rajabhat Suan Sunandha’s Learning Center in Samutsongkram</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chonmapat%20Torasa">Chonmapat Torasa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the performance of electricity generation and consumption from solar generator installed at Rajabhat Suan Sunandha’s learning center in Samutsongkram.

These results demonstrate the proposed receiver front-end architecture is very promising for 60 GHz direct-conversion transceiver applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CMOS" title="CMOS">CMOS</a>, <a href="https://publications.waset.org/abstracts/search?q=60%20GHz" title=" 60 GHz"> 60 GHz</a>, <a href="https://publications.waset.org/abstracts/search?q=direct-conversion%20transceiver" title=" direct-conversion transceiver"> direct-conversion transceiver</a>, <a href="https://publications.waset.org/abstracts/search?q=LNA" title=" LNA"> LNA</a>, <a href="https://publications.waset.org/abstracts/search?q=down-conversion%20mixer" title=" down-conversion mixer"> down-conversion mixer</a>, <a href="https://publications.waset.org/abstracts/search?q=marchand%20balun" title=" marchand balun"> marchand balun</a>, <a href="https://publications.waset.org/abstracts/search?q=current-reused" title=" current-reused"> current-reused</a> </p> <a href="https://publications.waset.org/abstracts/32604/a-low-power-low-noise-and-high-gain-5866-ghz-cmos-receiver-front-end-for-short-range-high-speed-wireless-communications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32604.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">452</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">61</span> Parallel Operated Rotary Frequency Converters within a Ship Micro-Grid System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamdy%20Ahmed%20Ashour">Hamdy Ahmed Ashour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper studies the parallel operation of rotary frequency converters which can be used within a ship micro-grid system and also to supply ships and equipment in a harbour during off-sail and maintenance periods with their suitable voltage and frequency requirements in order to overcome the possible associated problems of overloading on a single converter. The paper theoretically and experimentally investigated the operation of 3-ph induction motor / 3-ph synchronous generator based rotary converters set. Concept of operation and merits of such converters has been discussed. Overall dynamic simulation model of two parallel operated rotary converters has been developed. Active and reactive load sharing of the two converters has been analyzed. Experimental setup has been implemented for proof of concept and practical validation. Simulation and experimental results have been obtained and well correlated; showing how the rotary converters based setup can be manipulated to achieve different requirements of operating conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experimental" title="experimental">experimental</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency-converters" title=" frequency-converters"> frequency-converters</a>, <a href="https://publications.waset.org/abstracts/search?q=load-sharing" title=" load-sharing"> load-sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=marine-applications" title=" marine-applications"> marine-applications</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=synchronization" title=" synchronization"> synchronization</a> </p> <a href="https://publications.waset.org/abstracts/44199/parallel-operated-rotary-frequency-converters-within-a-ship-micro-grid-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44199.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">455</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">60</span> Adaptive Power Control of the City Bus Integrated Photovoltaic System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Kacejko">Piotr Kacejko</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariusz%20Duk"> Mariusz Duk</a>, <a href="https://publications.waset.org/abstracts/search?q=Miroslaw%20Wendeker"> Miroslaw Wendeker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an adaptive controller to track the maximum power point of a photovoltaic modules (PV) under fast irradiation change on the city-bus roof. Photovoltaic systems have been a prominent option as an additional energy source for vehicles. The Municipal Transport Company (MPK) in Lublin has installed photovoltaic panels on its buses roofs. The solar panels turn solar energy into electric energy and are used to load the buses electric equipment. This decreases the buses alternators load, leading to lower fuel consumption and bringing both economic and ecological profits. A DC–DC boost converter is selected as the power conditioning unit to coordinate the operating point of the system. In addition to the conversion efficiency of a photovoltaic panel, the maximum power point tracking (MPPT) method also plays a main role to harvest most energy out of the sun. The MPPT unit on a moving vehicle must keep tracking accuracy high in order to compensate rapid change of irradiation change due to dynamic motion of the vehicle. Maximum power point track controllers should be used to increase efficiency and power output of solar panels under changing environmental factors. There are several different control algorithms in the literature developed for maximum power point tracking. However, energy performances of MPPT algorithms are not clarified for vehicle applications that cause rapid changes of environmental factors. In this study, an adaptive MPPT algorithm is examined at real ambient conditions. PV modules are mounted on a moving city bus designed to test the solar systems on a moving vehicle. Some problems of a PV system associated with a moving vehicle are addressed. The proposed algorithm uses a scanning technique to determine the maximum power delivering capacity of the panel at a given operating condition and controls the PV panel. The aim of control algorithm was matching the impedance of the PV modules by controlling the duty cycle of the internal switch, regardless of changes of the parameters of the object of control and its outer environment. Presented algorithm was capable of reaching the aim of control. The structure of an adaptive controller was simplified on purpose. Since such a simple controller, armed only with an ability to learn, a more complex structure of an algorithm can only improve the result. The presented adaptive control system of the PV system is a general solution and can be used for other types of PV systems of both high and low power. Experimental results obtained from comparison of algorithms by a motion loop are presented and discussed. Experimental results are presented for fast change in irradiation and partial shading conditions. The results obtained clearly show that the proposed method is simple to implement with minimum tracking time and high tracking efficiency proving superior to the proposed method.
