Abstract
A new ZVZCS Single-Stage Power-Factor-Correction(PFC) AC/DC converter with boost PFC cell is integrated with voltage doubler rectified asymmetrical half-bridge(VDRAHB) is proposed in this paper. The proposed converter features good power factor correction, low current harmonic distortions, tight output regulations and low voltage of link capacitor. An 85W prototype was implemented to show that it meets the harmonic requirements and standards satisfactorily with nearly unity power factor and high efficiency over universal input.
