Two Switches Flyback Type Soft-Switching DC-DC Converter using Snubber Energy Regenerative Circuits with Auxiliary Transformers

Abstract

This paper presents a novel type flyback DC-DC converter using snubber energy regenerative circuit. The proposed snubber regenerative circuit consists of passive circuit components such as auxiliary transformers, inductors, capacitors and diodes, and has a high reliability. The operation principle is described on the basis of simulation evaluations. The turn-on and -off soft-switching operations of active power switch can be achieved by the proposed new snubber circuits with auxiliary transformers
