A new AC-DC converter using bridgeless SEPIC

A new bridgeless power factor correction circuit (PFC) based on single ended primary inductance converter (SEPIC) is proposed. The number of component conducted at each subinterval mode is reduced compared to the existing topologies. Analysis of the converter operated in discontinuous-conduction mod...

More Information
Summary:A new bridgeless power factor correction circuit (PFC) based on single ended primary inductance converter (SEPIC) is proposed. The number of component conducted at each subinterval mode is reduced compared to the existing topologies. Analysis of the converter operated in discontinuous-conduction mode (DCM) is discussed. Experimental circuit for the proposed converter is developed with universal input voltage capability for 50V DC output voltage connected to 100W load. The simulation and experimental results are presented to show the performances of the proposed circuit.
