[Full Text]

Index Terms: DC–DC converter, high-voltage gain, zero-voltage switching (ZVS), zero-current switching (ZCS), PV module.



Abstract: This paper proposes a ZVZCS asymmetrical full-bridge converter with high-voltage gain by different loads. The proposed converter features high-voltage gain, fixed switching frequency and clamped voltages across power switches and output diodes. The control of the converter is implemented with the asymmetrical pulse width modulation technique. The converter achieves zero-voltages witching (ZVS) of all power switches and Zero-current switching (ZCS) of output diodes. The energy shortage and the atmosphere pollution have led to more researches in renewable sources of energy. In this paper, PV module is modelled using Matlab/Simulink. The modeled PV cell act as the dc input source for the converter. The computer simulation of the converter is done using MATLAB/SIMULINK and is interfaced with the mathematical model of PV cell and various waveforms are presented in the paper.
