Özet

© Oriental Scientific Publishing Company.In this study, a novel resonance-based single-switch and single-stage power factor correction (PFC) converter is proposed. This converter achieves soft switching (SS), thereby minimizing switching losses. The converter draws current from the line in a sinusoidal form during each switching period, which provides high PFC with decreased electromagnetic interference. Furthermore, the proposed converter transfers most of the input energy directly to the output, providing direct power transfer with high efficiency using a forward-flyback converter. The rest of the input energy is transferred to the output via a flyback converter to obtain high output regulation. At this converter, PFC circuit, forward and flyback converters share only one switch. The theoretical analysis of this resonance-based single-switch and single-stage PFC converter is verified by a prototype output of 200 W/120 V with a 100-kHz switching frequency.
