Bridgeless SEPIC PFC Converter

摘要：

　　A new bridgeless power factor correction (PFC) converter is proposed in this paper.The proposed converter is based on single-ended primary inductor converter (SEPIC).In the proposed converter,conduction losses are reduced and efficiency is improved by eliminating bridge diodes.In addition,input current ripple is significantly reduced by utilizing coupled inductors.Like a conventional SEPIC PFC converter,the proposed converter provides almost unity power factor (PF).Steady-state analysis of the proposed converter is performed.Experimental results based on a prototype are also provided to verify the effectiveness and feasibility of the proposed converter.
