Abstract :
In this paper, a bridgeless PFC converter in which two diodes in the rectifier-bridge are replaced by two switches is proposed, and its operating principles in both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) are analyzed in detailed. The simulation results verify the theoretical analysis. Compared to other bridgeless PFC converter, the proposed converter has lower voltage stress, higher static gain and is more suitable for the universal input voltage application.
