A novel zero-voltage-switching (ZVS) PWM half-bridge power converter is presented. The proposed power converter consists of a conventional half-bridge power converter and two added switches in series with the secondary rectifier diodes. This power converter is controlled by PWM of the main switches using a novel switching sequence with constant switching frequency. The zero voltage switching of the main switches is maintained by partial resonance during the interval where both the main switches are off, and the secondary switches turn on and off with zero voltage and zero current. The operation of this power converter is described by use of equivalent circuits and is verified by experiments.<>
