Abstract :
A novel full-bridge PWM DC/DC converter with controlled secondary side rectifier using secondary snubber is presented in this paper. Circulating current of the converter was eliminated and soft switching for all power switches of the inverter is achieved for full load range from no-load to short circuit by using controlled rectifier and snubber on the secondary side. The principle of operation is explained and analyzed and the experimental results on a 4,5kW, 100 kHz laboratory model of the converter are presented.
