LEDs are low-voltage light sources, requiring a constant DC voltage or current to operate optimally. LEDs, therefore, require a device that can convert incoming AC power to the proper DC voltage, and regulate the current flowing through the LED during operation. Proposed topology has a front end converter. It is an AC-DC rectifier that works on bridgeless boost topology which shapes the input current waveform. The front end converter is followed by a DC-DC converter which provides a constant DC voltage across the LEDs. A 12V AC input is given to the input of frontend converter which rectifies and boost the voltage to 24v DC and gives it to the DC-DC converter. The DC-DC converter converts the 24V DC and regulates this constant DC voltage across the LEDs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridgeless%20rectifier" title="bridgeless rectifier">bridgeless rectifier</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20factor%20correction%28PFC%29" title=" power factor correction(PFC)"> power factor correction(PFC)</a>, <a href="https://publications.waset.org/abstracts/search?q=SC%20converter" title=" SC converter"> SC converter</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20harmonic%20distortion%20%28THD%29" title=" total harmonic distortion (THD)"> total harmonic distortion (THD)</a> </p> <a href="https://publications.waset.org/abstracts/53400/analysis-of-a-power-factor-correction-converter-for-light-emitting-diode-driver-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53400.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">873</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">6329</span> 1 kW Power Factor Correction Soft Switching Boost Converter with an Active Snubber Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yakup%20Sahin">Yakup Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Naim%20Suleyman%20Ting"> Naim Suleyman Ting</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Aksoy"> Ismail Aksoy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A 1 kW power factor correction boost converter with an active snubber cell is presented in this paper.

Basically, this high step-up DC/DC converter is an appealing interface for solar applications. The proposed topology takes advantage of using coupled inductors. Due to the leakage inductances of these coupled inductors, the power MOSFET has the zero current switching (ZCS) condition, which results in decreased switching losses. This will substantially improve the overall efficiency of the power converter. Furthermore, employing coupled inductors has led to a higher voltage gain. Theoretical analysis and experimental results of a 100W 20V/220V prototype are presented to verify the superior performance of the proposed DC/DC converter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coupled%20inductors" title="coupled inductors">coupled inductors</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20step-up%20DC%2FDC%20converter" title=" high step-up DC/DC converter"> high step-up DC/DC converter</a>, <a href="https://publications.waset.org/abstracts/search?q=zero-current%20switching" title=" zero-current switching"> zero-current switching</a>, <a href="https://publications.waset.org/abstracts/search?q=Cuk%20converter" title=" Cuk converter"> Cuk converter</a>, <a href="https://publications.waset.org/abstracts/search?q=SEPIC%20converter" title=" SEPIC converter"> SEPIC converter</a> </p> <a href="https://publications.waset.org/abstracts/107674/a-single-switch-high-step-up-dcdc-converter-with-zero-current-switching-condition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107674.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">719</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">6327</span> A Single Phase ZVT-ZCT Power Factor Correction Boost Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yakup%20Sahin">Yakup Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Naim%20Suleyman%20Ting"> Naim Suleyman Ting</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Aksoy"> Ismail Aksoy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a single phase soft switched Zero Voltage Transition and Zero Current Transition (ZVT-ZCT) Power Factor Correction (PFC) boost converter is proposed. In the proposed PFC converter, the main switch turns on with ZVT and turns off with ZCT without any additional voltage or current stresses. Auxiliary switch turns on and off with zero current switching (ZCS). Also, the main diode turns on with zero voltage switching (ZVS) and turns off with ZCS.

Furthermore, it is shown that performance of boost converter with MPPT operation fails under low load resistance connection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boost%20converter" title="boost converter">boost converter</a>, <a href="https://publications.waset.org/abstracts/search?q=incremental%20conductance%20%28Inc-Cond%29" title=" incremental conductance (Inc-Cond)"> incremental conductance (Inc-Cond)</a>, <a href="https://publications.waset.org/abstracts/search?q=MPPT" title=" MPPT"> MPPT</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20panel" title=" solar panel"> solar panel</a> </p> <a href="https://publications.waset.org/abstracts/18408/design-and-implementation-of-dc-dc-converter-with-inc-cond-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18408.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">1046</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">6322</span> Design of Direct Power Controller for a High Power Neutral Point Clamped Converter Using Real-Time Simulator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amin%20Zabihinejad">Amin Zabihinejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Viarouge"> Philippe Viarouge</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a direct power control (DPC) strategies have been investigated in order to control a high power AC/DC converter with time variable load. This converter is composed of a three level three phase neutral point clamped (NPC) converter as rectifier and an H-bridge four quadrant current control converter. In the high power application, controller not only must adjust the desired outputs but also decrease the level of distortions which are injected to the network from the converter. Regarding this reason and nonlinearity of the power electronic converter, the conventional controllers cannot achieve appropriate responses. In this research, the precise mathematical analysis has been employed to design the appropriate controller in order to control the time variable load. A DPC controller has been proposed and simulated using Matlab/Simulink. In order to verify the simulation result, a real-time simulator- OPAL-RT- has been employed. In this paper, the dynamic response and stability of the high power NPC with variable load has been investigated and compared with conventional types using a real-time simulator. The results proved that the DPC controller is more stable and has more precise outputs in comparison with the conventional controller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20power%20control" title="direct power control">direct power control</a>, <a href="https://publications.waset.org/abstracts/search?q=three%20level%20rectifier" title=" three level rectifier"> three level rectifier</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20simulator" title=" real time simulator"> real time simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20power%20application" title=" high power application"> high power application</a> </p> <a href="https://publications.waset.org/abstracts/13864/design-of-direct-power-controller-for-a-high-power-neutral-point-clamped-converter-using-real-time-simulator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13864.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">517</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">6321</span> Optimisation of Photovoltaic Array with DC-DC Converter Groups</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Soltani">Fatma Soltani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In power electronics the DC-DC converters or choppers are now employed in large areas, particularly in the field of electricity generation by wind and solar energy conversion. Photovoltaic generators (GPV) can deliver maximum power for a point on the characteristic P = f (Vpv), called maximum power point (MPP), or climatic variations, entraiment fluctuation PPM. To remedy this problem is interposed between the generator and receiver a DC-DC converter. The converter is usually used a simple MOSFET chopper. However, the MOSFET can be applied in the field of low power when you need a high switching frequency but becomes highly dissipative when should block large voltages For PV generators medium and high power, the use of IGBT chopper is by far the most recommended. To reduce stress on semiconductor components using several choppers series connected in parallel is known as interleaved chopper. These choppers lead to rotas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=converter%20DC-DC%20entrelaced%01%02%01" title="converter DC-DC entrelaced">converter DC-DC entrelaced</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20generators" title=" photovoltaic generators"> photovoltaic generators</a>, <a href="https://publications.waset.org/abstracts/search?q=IGBT" title=" IGBT"> IGBT</a>, <a href="https://publications.waset.org/abstracts/search?q=optimisation" title=" optimisation"> optimisation</a> </p> <a href="https://publications.waset.org/abstracts/21869/optimisation-of-photovoltaic-array-with-dc-dc-converter-groups" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21869.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">539</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">6320</span> A 5-V to 30-V Current-Mode Boost Converter with Integrated Current Sensor and Power-on Protection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun%20Yu">Jun Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yat-Hei%20Lam"> Yat-Hei Lam</a>, <a href="https://publications.waset.org/abstracts/search?q=Boris%20Grinberg"> Boris Grinberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Chai%20Tshun%20Chuan"> Kevin Chai Tshun Chuan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a 5-V to 30-V current-mode boost converter for powering the drive circuit of a micro-electro-mechanical sensor.

It degrades the performance of a switching converter. Therefore, it is an essential requirement to mitigate EMI noise of high performance converter. Moreover, it includes two types of emission such as common mode (CM) and differential mode (DM) noise. CM noise is due to parasitic capacitance present in a converter and DM noise is caused by switching current. However, there is dire need to understand the main cause of EMI noise. Hence, we propose a novel method to predict conducted EMI noise of different converter topologies during early stage. This paper also presents the comparison of conducted electromagnetic interference (EMI) noise due to different SMPS topologies. We also make an attempt to develop an EMI noise model for a converter which allows detailed performance analysis. The proposed method is applied to different converter, as an example, and experimental results are verified the novel prediction technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EMI" title="EMI">EMI</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20interference" title=" electromagnetic interference"> electromagnetic interference</a>, <a href="https://publications.waset.org/abstracts/search?q=SMPS" title=" SMPS"> SMPS</a>, <a href="https://publications.waset.org/abstracts/search?q=switch-mode%20power%20supply" title=" switch-mode power supply"> switch-mode power supply</a>, <a href="https://publications.waset.org/abstracts/search?q=common%20mode" title=" common mode"> common mode</a>, <a href="https://publications.waset.org/abstracts/search?q=CM" title=" CM"> CM</a>, <a href="https://publications.waset.org/abstracts/search?q=differential%20mode" title=" differential mode"> differential mode</a>, <a href="https://publications.waset.org/abstracts/search?q=DM" title=" DM"> DM</a>, <a href="https://publications.waset.org/abstracts/search?q=noise" title=" noise"> noise</a> </p> <a href="https://publications.waset.org/abstracts/42100/prediction-of-conducted-emi-noise-in-a-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42100.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">1208</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">6317</span> Performance Analysis of Transformerless DC-DC Boost Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nidhi%20Vijay">Nidhi Vijay</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20K.%20Sharma"> A.

DC-DC boost converters are now being used all over the world for rapid transit system. Although these provide high efficiency, smooth control, fast response and regeneration, conventional DC-DC boost converters are unable to provide high step up voltage gain due to effect of power switches, rectifier diodes and equivalent series resistance of inductor and capacitor. This paper proposes new transformerless dc-dc converters to achieve high step up voltage gain as compared to the conventional converter without an extremely high duty ratio. Only one power stage is used in this converter. Steady-state analysis of voltage gain is discussed in brief.

The converter is based on the LM2596 regulator and designed to step down the input voltage of +16.8V to +12V, +5V, and +3.3V output, which are suitable for the nanosatellite's various subsystems. The load switch is based on MOSFET and is used to turn on or off the power supply to a particular load and protect the nanosatellite from power surges. A prototype of a +12V DC/DC buck converter with a high side load switch has been realized and tested, which meets our requirements and shows a good efficiency of 89%. In addition, the prototype features a capacitor between the source and gate of the MOSFET, which has effectively reduced the inrush current, demonstrating the effectiveness of this approach in reducing surges of current when the load is connected. The output current and voltage were measured at 0.7A and 11.89V, respectively, making this design suitable for use in low-cost educational nanosatellites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC%2FDC%20buck%20converter" title="DC/DC buck converter">DC/DC buck converter</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20switch" title=" load switch"> load switch</a>, <a href="https://publications.waset.org/abstracts/search?q=LM2596" title=" LM2596"> LM2596</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20power%20subsystems" title=" electrical power subsystems"> electrical power subsystems</a>, <a href="https://publications.waset.org/abstracts/search?q=nanosatellite" title=" nanosatellite"> nanosatellite</a>, <a href="https://publications.waset.org/abstracts/search?q=inrush%20current" title=" inrush current"> inrush current</a> </p> <a href="https://publications.waset.org/abstracts/166405/integration-of-a-load-switch-with-dcdc-buck-converter-for-power-distribution-in-low-cost-educational-nanosatellite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166405.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">101</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">6315</span> Analysis of DC\DC Converter of Photovoltaic System with MPPT Algorithms Comparison</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Badr%20M.%20Alshammari">Badr M.

In this manner, no need for a Maximum Power Point Tracking (MPPT) unit to set the reference of the PV terminal voltage. This strategy overcomes the stability issues of the DC microgrid as the response of converters is superior compared to the conventional strategies.

DC connection can solve many problems that AC connection faces, such as the grid-connection and power transmission, and DC connection is the tendency. DC/DC converter as the most important device in the system has become one of the hot spots recently. The paper proposes a centralized DC/DC converter which uses Boost Full Bridge Isolated DC/DC Converter(BFBIC) topology and combination through input parallel output series(IPOS) method to improve power capacity and output voltage to match with the HVDC grid voltage. Meanwhile, it adopts input current sharing control strategy to realize input current and output voltage balance. A 卤30kV/1MW system is modeled in MATLAB/SIMULINK, and a downscaled 卤10kV/200kW DC/DC converter platform is built to verify the proposed topology and control strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20generation" title="photovoltaic generation">photovoltaic generation</a>, <a href="https://publications.waset.org/abstracts/search?q=cascaded%20dc%2Fdc%20converter" title=" cascaded dc/dc converter"> cascaded dc/dc converter</a>, <a href="https://publications.waset.org/abstracts/search?q=galvanic%20isolation" title=" galvanic isolation"> galvanic isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=high-voltage" title="high-voltage">high-voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20current%20%28HVDC%29" title=" direct current (HVDC)"> direct current (HVDC)</a> </p> <a href="https://publications.waset.org/abstracts/72072/large-scale-photovoltaic-generation-system-connected-to-hvdc-grid-with-centralized-high-voltage-and-high-power-dcdc-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72072.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">442</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">6310</span> Study on the Impact of Default Converter on the Quality of Energy Produced by DFIG Based Wind Turbine </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Zerzouri">N.

The usage of this kind of converters come from its advantage of non-reverse polarity at outputs. As capacitors charge and discharge through inductance, peak current does not occur on capacitors. Therefore, the efficiency will be high compared to buck-boost converters. In this study, the converter (SEPIC) is designed to be operated with Internal Model Controller (IMC). The traditional controllers like Proportional Integral Controller are not preferred as its linearity behavior. Hence IMC is designed for this converter. This controller is a model-based control and provides more robustness and better set point monitoring. Moreover, it can be used for an unstable process where the conventional controller cannot handle the dynamic operation. Matlab/Simulink environment is used to simulate the converter and its controller, then, the results are shown and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC%2FDC%20converter" title="DC/DC converter">DC/DC converter</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20ended%20primary%20inductance%20converter" title=" single ended primary inductance converter"> single ended primary inductance converter</a>, <a href="https://publications.waset.org/abstracts/search?q=SEPIC" title=" SEPIC"> SEPIC</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20model%20controller" title=" internal model controller"> internal model controller</a>, <a href="https://publications.waset.org/abstracts/search?q=IMC" title=" IMC"> IMC</a>, <a href="https://publications.waset.org/abstracts/search?q=switched%20mode%20power%20supply" title=" switched mode power supply"> switched mode power supply</a> </p> <a href="https://publications.waset.org/abstracts/130008/single-ended-primary-inductance-converter-with-internal-model-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130008.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">628</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">6308</span> A High Step-Up DC-DC Converter for Renewable Energy System Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sopida%20Vacharasukpo">Sopida Vacharasukpo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudarat%20Khwan-On"> Sudarat Khwan-On</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a high step-up DC-DC converter topology for renewable energy system applications. The proposed converter employs only a single power switch instead of using several switches. Compared to the conventional DC-DC step-up converters the higher voltage gain with small output ripples can be achieved by using the proposed high step-up DC-DC converter topology. It can step up the low input voltage (20-50Vdc) generated from the photovoltaic modules to the high output voltage level approximately 600Vdc in order to supply the three-phase inverter fed the three-phase motor drive. In this paper, the operating principle of the proposed converter topology and its control strategy under the continuous conduction mode (CCM) are described. Finally, simulation results are shown to demonstrate the effectiveness of the proposed high step-up DC-DC converter with its control strategy to increase the voltage step-up conversion ratio. <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=high%20step-up%20ratio" title=" high step-up ratio"> high step-up ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20switch" title=" single switch "> single switch </a> </p> <a href="https://publications.waset.org/abstracts/9443/a-high-step-up-dc-dc-converter-for-renewable-energy-system-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9443.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">1193</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">6307</span> An Improved Photovolatic System Balancer Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chih-Chiang%20Hua">Chih-Chiang Hua</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Hsiung%20Fang"> Yi-Hsiung Fang</a>, <a href="https://publications.waset.org/abstracts/search?q=Cyuan-Jyun%20Wong"> Cyuan-Jyun Wong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An improved PV balancer for photovoltaic applications is proposed in this paper.

Thus, the PV system can implement maximum power point tracking (MPPT) independently for each module whether it is under shading, different irradiation or degradation of PV cell. In addition, the cost of PV balancer can be reduced due to the low power rating of converter.

This device is intended to be implemented in a variable speed wind energy conversion system connected to the grid. Firstly, we developed a model of matrix converter, controlled by the Venturini modulation technique. In order to control the power exchanged between the stator of the DFIG and the grid, a control law is synthesized using a high order sliding mode controller. The use of this method provides very satisfactory performance for the DFIG control. The overall strategy has been validated on a 2-MW wind turbine driven a DFIG using the Matlab/Simulink. <p class="card-text"><strong>Keywords:</strong> <a
