Abstract :
A new soft-switching PWM full-bridge converter is proposed in this paper. The proposed converter has zero voltage switching (ZVS) in all its switches with fewer conduction losses than other ZVS-PWM full-bridge converters, due to a novel auxiliary circuit scheme. In the paper, the operation of the proposed converter is explained in detail, its features and design are discussed, and experimental results obtained from a lab prototype are presented.
