A passive auxiliary network consisting of capacitors and inductors can be added to the conventional phase-shifted full-bridge (FB) converter to achieve zero-voltage switching for all primary switches in the whole load range. Meanwhile, accurate loss analysis facilitates the proposal of novel methods to reduce losses, optimisation of converter topology and improvement of the efficiency. In this study,...
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...
