摘要
针对传统仅使用功率因数校正(PFC)变换器设计的AC-DC LED驱动电源存在由2倍工频输出电流纹波造成的频闪问题,提出了一种基于Cuk PFC变换器的无频闪LED驱动电源。通过简单的电压模控制,所提变换器可以同时实现功率因数校正和低2倍工频输出电流纹波,实现高功率因数和LED无频闪。最后,通过一台11.2 W的实验样机验证了理论分析的正确性。
In order to solve the problem of flicker caused by double-line frequency output current ripple in the AC-DC LED driving circuit designed by traditional power factor correction(PFC)converter,a flicker-free LED driving circuit based on Cuk PFC converter was proposed.Through a simple voltage mode control,the proposed converter could simultaneously realize power factor correction and low double-order line frequency current ripple,and achieved high power factor and flicker-free LED driving circuit.Finally,a 11.2 W experimental prototype was presented to verify the correctness of the theoretical analysis of the proposed converter.
