Abstract

A new single stage AC/DC converter with a high power factor is proposed. The proposed converter gives good power factor correction, low current harmonic distortions, and tight output regulations. This converter also has an high efficiency by employing Active-clamp method and synchronous rectifiers. To verify performances of the proposed converter, 90W-converter is designed. This prototype meets the IEC555-2 requirements satisfactorily with nearly unity power factor.
