Abstract :
A soft-switched full-bridge (FB) converter that features zero-voltage-switching (ZVS) of the bridge switches over a wide output-load range is introduced. The proposed converter achieves ZVS with substantially reduced duty-cycle loss and circulating current. The control of the proposed converter can be implemented either with the phase-shift or pulsewidth modulated (PWM) technique. The performance of the proposed topology was verified on a 2-kW (48-V/40-A) experimental PWM FB converter prototype operating at 120 kHz from a 380-V dc input
