A full-bridge PWM DC/DC converter with controlled output rectifier is presented in this paper. Soft switching for all power switches is achieved by using controlled output rectifier with new lossless energy recovery turn-off snubber on the secondary side of the converter. No circulating current is occurred in the proposed converter with used new control method. The principle of operation is explained and analyzed and the experimental results on a 1.2kW, 50 kHz laboratory model of the converter are presented.
