Novel soft switching DC/DC converter with active rectifier for wide load range

摘要

This paper is dedicated to a special high frequency DC/DC converter with a secondary side active rectifier, which in cooperation with a novel type of active lossless snubber ensures required conditions for soft switching of all transistor switches of the converter in a wide load range. Theoretical analysis of DC/DC converter with active rectifier is done, and operation principle of the proposed soft switching DC/DC converter with active rectifier and active snubber is described. Experimental results obtained on laboratory model of proposed soft switching DC/DC converter are presented.
