| Abstract: | Single-stage line-coupled ac/dc converter with high power factor and ripple-free input current is proposed. The proposed power factor correction circuit can achieve high power factor and ripple-free input current using a coupled inductor. Experimental results for a 400?W converter at a constant switching frequency of 100?kHz are obtained to show the performance of the proposed converter. |
