Abstract: A Phase Shifted-Zero Voltage Switching (PS-ZVS) Full Bridge DC-DC Converter (FBDCC) over a wide load variation is proposed. The proposed converter is designed for high efficiency, small size and low switching stress also for no load to wide load variations. In this converter Phase Shifted Pulse Width Modulation (PS-PWM) control is used to reduce the ringing. The transformer leakage inductance is used for resonance where losses are reduced and efficiency is more. The operation of the proposed converter is simulated using Pspice software and verified on a 1 kW (kW) experimental prototype converter operating at 25 kHz with 25 V dc input.
