A phase-shift full-bridge zero-voltage-switching (ZVS) pulse-width-modulated (PWM) converter with commutation capacitor and inductor-capacitor (LC) auxiliary circuit is proposed. This converter contains the advantages of small rectifier voltage oscillation as well as no duty cycle loss, and realises ZVS for all primary switches over a wide load range. In this study, the mechanism of the rectifier voltage oscillation is discussed in detail. The operation principle of the circuit is described and design considerations of the converter are discussed. Finally, the experimental results from a 650 W/28 V, 100 kHz prototype are given to confirm the operation, validity and features of the proposed converter.
