A Comparative Study of Conventional and T-Type ZVS-PWM Full-Bridge Converters

The ZVS T-type DC-DC converter has been proposed as an alternative to the conventional ZVS-PWM full-bridge (FB) converter. Although it has a number of advantageous features, the ZVS T-type DC-DC converter is not well known among power electronic engineers and the topology has thus been neglected. In the paper, the operation of the DC-DC ZVS T-type converter is reviewed and contrasted to that of the conventional ZVS-PWM-FB DC-DC converter. Results obtained from prototypes of each converter topology are then presented, compared, and discussed, and conclusions which converter is superior for particular applications are made.
