Abstract

This paper presents a new structure of single-stage flyback power factor correction (PFC) converter with a controllable couplednegative magnetic feedback (NMF) winding. NMF winding is used to reduce the bulk capacitor voltage at high line voltages andlight loads. However, it would cause line current distortion at zero crossing condition. In the proposed circuit, a series winding isused with NMF inductor to eliminate the NMF inductor at low line voltages. As a result, the dead angle of the input current, nearzero voltage crossing, is eliminated and the power factor is increased. The presented experimental results of the proposed PFCconverter confirm the integrity of the new idea and the theoretical analysis.
