摘要: A new reduced voltage stress soft switching PWM current fed Full-Bridge DC-DC converter for fuel cells and photovoltaic applications is proposed in this study. The snubber cell provides Zero Voltage Transition (ZVT) turn on Switching (ZVS) off together main switches the converter. stresses of are turning them became better by adding an extra passive component. Besides, all components operate under switching, or auxiliary component quite acceptable level, devices do not have any additional stresses. In addition, simplified structure makes novel easy to control. Detailed analysis synthesis introduced, usefulness design confirmed simulation studies a 1.5 kW 25 kHz full bridge
