Abstract

A novel three-level zero-voltage zero current switching (ZVZCS) DC/DC converter is presented in this paper. In order to achieve zero current soft switching and eliminate the high voltage stress on the rectifiers, a tapped inductor is introduced to reset the primary circulation current during the freewheeling stage. The resetting voltage and the time can be regulated conveniently by setting the turn ratios of the tapped inductor, and no high voltage stress in secondary side appears. The principle and operation modes are analyzed. Experimental results based on a 500 W/100 kHz prototype are given to verify the validity of the proposed converter
