A Modified SEPIC Converter with Extended Gain for Universal Input Voltage Applications

Author Name : Ansu Alex, Anish Benny

ABSTRACT A high-power-factor rectifier suitable for universal line base on a modified version of the single-ended primary inductance converter (SEPIC) is presented in this paper. The voltage multiplier technique is applied to the classical SEPIC circuit, obtaining new operation characteristics as low-switch-voltage operation and high static gain at low line voltage. The operation analysis and design procedure, obtained from a 10 W universal line power-factor-correction prototype of the proposed converter are presented. The theoretical analysis and simulation results obtained with the proposed structure are compared with the classical boost topology.
