Abstract：A Buck-Flyback single-stage power factor correction (PFC) converter for LED driving circuit with primary-side control is proposed in this paper. The operation principle of the main circuit and the principle of the primary-side constant current control strategy are analyzed. It consists of input Buck converter and output Flyback converter with single switch. The input Buck converter achieves PFC, and output Flyback converter controls LED current. Without the photocoupler and secondary current sensing circuit, the LED driving circuit with single switch and single controller can realize high power factor, high efficiency, low cost and flicker-free. Finally, a 36W experimental prototype was designed to verify the correctness of the theoretical analysis.
