This paper deals with the full bridge zero-voltage-switching PWM (FB-ZVS-PWM) dc-dc converter with output capacitive filter, whose main attributes are (a) soft commutation, (b) pulse width modulation by phase shifting, (c) input and output voltage source characteristic, (d) symmetric operation of the isolation transformer, (e) high efficiency, and (f) high power density. Circuit operation and theoretical analysis are included in the paper, along with experimental results taken from a laboratory prototype; with 400 Vdc input voltage, 400 Vdc output voltage, output power of 1 kW, and switching frequency of 40 kHz. The measured efficiency was 94.8% at full load and 93.9% at 400 W.
