Abstract—DCM Flyback PFC converter is mainly used in medium and low power applications, having such advantages as zero-current turning on of switch, no reverse recovery of diode and high PF. At the time power electronics widely used today, passive components volume limits the improvement of power density. This paper derives the expressions of the switching turn-on time and the input current of DCM Flyback PFC converter, and based on which, a variable duty control is proposed so as to make the energy storage capacitor reduce to the original 65.6% at the same voltage ripple level while PF is not less than 0.9. The simulation results from a 200W universal input prototype are given to verify the effectiveness of the analysis.
