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 MatlabSimulink. The modeled PV cell act as the dc input source for the converter. The computer simulation of the converter is done using MATLABSIMULINK and is interfaced with the mathematical model of PV cell and various waveforms are presented in the paper.
