Received Jan 8, 2018 Revised Mar 23, 2018 Accepted Apr 11, 2018 Distributed energy source based electricity generation is an essential factor for the economic growth and development of a country. The photovoltaic, fuel cell and battery based power generation offer a high voltage gain. The DC-DC CUK converter based on both buck and boost mode of operation is proposed for high gain dc link voltag...

MODULARIZED MULTILEVEL AND Z-SOURCE POWER CONVERTER AS RENEWABLE ENERGY INTERFACE FOR VEHICLE AND GRID-CONNECTED APPLICATIONS By Dong Cao Due the energy crisis and increased oil price, renewable energy sources such as photovoltaic panel, wind turbine, or thermoelectric generation module, are used more and more widely for vehicle and grid-connected applications. However, the output of these rene...

this paper presents the new topology of three phase on line uninterruptible power supply (ups) by employing t-source inverter (tsi) with maximum constant boost pulse width modulation (pwm) control and the results are compared with the conventional uninterruptible power supply (ups). the conventional ups consists of voltage source inverter (vsi) with step up transformer or dc-dc booster which de...

To link DC power sources to an AC grid, converters are needed. Inverters the electronic devices, which used for this purpose. Conventional inverters employ harmonic filters and transformers that lossy expensive. Multilevel (MLIs) alternative conventional ones, proposing reduced total distortion (THD), increased range of control, inductor-less design. They generate a stepped waveform, with close...

This paper presents a comparative analysis of the Z-source inverter with two different control techniques namely the simple boost control and the maximum constant boost control with third harmonic injection. The Z-source inverter has the capability to buck-boost the input voltage without any intermediate boost conversion stage. It utilizes the shoot-through states effectively to boost the input...

This paper presents a method of enhancing the performance of a four-phase switched reluctance motor by using capacitors to produce additional supply voltage during the rise and fall periods of a motor phase current. The voltage rating of the inverter components increases and extra capacitor/diode combinations are needed. The operation and analysis of a series voltage boost circuit are detailed ...
