Abstract

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.
