Abstract

In this paper, a new single-switch soft-switching isolated converter is introduced. In the proposed converter, the transformer parasitic elements are used as resonant elements to transfer energy and to attain soft-switching condition. The proposed converter does not require output inductor just like the flyback converter, and the transformer core does not store energy just like the forward converter. The proposed converter is analyzed and its advantages over conventional converters are discussed. Also, experimental results are presented to justify the validity of theoretical analysis.
