Abstract

This paper presents a new single stage power factor corrected full bridge AC/DC converter operated with zero switching losses and has a simple control circuitry. This converter has only a few additional components compared to the nonpower factor corrected circuits: an additional transformer winding, small inductor and three diodes. This circuit allows the output voltage regulation and input current shaping with single stage and one control chip, Analytical, simulation and experimental results confirm the feasibility, and demonstrate the good efficiency and close to unity power factor
