Simulation Of Bridgeless Sepic Converter With Power Factor Correction Fed Dc Motor

Abstract: In this project, the Single Ended Primary Inductor converter (sepic) is used to achieve high power factor with reduce input ripple current. The power factor correction is suffered from high conduction loss due to input bridge diode. The bridgeless sepic converter is used to avoid conduction loss. The input current ripple is reduced by using an additional winding and an auxiliary capacitor. In switching period, the input current is proportional to the input voltage and achieved near unity power.
