Abstract :
This paper presents a high efficiency single-stage power factor correction ac-dc converter with zero voltage switching (ZVS). The proposed converter meets the IEC 61000-3-2 regulations with near unity power factor and ripple free input current. It is a cost effective and competitive solution for 100 600 W applications where a two stage approach is costly and passive filters are not recommended (J. Qian and F.C. Lee, 2000). To derive the design equations, an analysis is carried out in which the converter is divided into two stages. This approach simplifies the study. Experimental results for a 200 W converter are presented and discussed in order to validate the study and verify the performance of the proposed converter
