摘要
Power factor correction (PFC) converter with a twice-line-frequency ripple cancellation converter (RCC) has attracted much attention due to its ability of twice-line-frequency output voltage ripple cancellation and high power conversion efficiency. The audio susceptibility of buck-type RCC operating in discontinuous conduction mode is derived and the effect of loop gain of RCC on the cancellation of twice-line-frequency output voltage ripple is studied. Experimental results of a 50 W prototype are presented to verify the analysis results.
