Abstract A secondary resonant circuit is introduced into the bridgeless Flyback power factor correction (PFC) converter, and a bridgeless dual resonant PFC converter is proposed in this paper. The turn-off current of switch decreases due to the resonance between the secondary leakage inductance of the transformer and the resonant capacitor. Therefore, the turn-off losses of switch are greatly reduced. Meanwhile, the secondary diodes turn off at zero current, which effectively suppressed the voltage spike and oscillation. The operation principle and characteristics of the proposed converter working in critical conduction mode (CRM) are analyzed. The design principles of the key parameters in the converter are also presented. Finally, experimental results verify the theoretical analysis of the proposed converter.
