Abstract

This paper proposes an output inductor-less active clamp forward converter employing current boost-up circuit for high power density adaptor. By applying the proposed current boost-up circuit, the proposed converter has low conduction loss and low voltage ringing of the secondary rectifier. This paper presents the analysis of the proposed converter and a comparison between the proposed converter and the conventional converter through experiment.
