A new single phase zero-current-switched (ZCS) single stage quasi-resonant converter (QRC) for power factor correction (PFC) is proposed. The converter provides a good power factor, has tight output regulation, and low line current harmonic distortion. The proposed converter is suitable for low power level power supplies with high efficiency and tightly regulated output voltage
