Paper Title:
Bridgeless SEPIC PFC Converter
  Abstract

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