A high-quality rectifier employing a coupled-inductor Sepic topology is described, featuring high-frequency insulation and low input current ripple. Moreover, sinusoidal and in-phase input current is obtained even with constant duty-cycle. The magnetic structure is simple and cheap, allowing considerable size and cost reduction. Converter analysis, design criteria of both power and control sections and experimental results are reported in the paper.

Abstract
A high-quality rectifier employing a coupled-inductor Sepic topology is described, featuring high-frequency insulation and low input current ripple. Moreover, sinusoidal and in-phase input current is obtained even with constant duty-cycle. The magnetic structure is simple and cheap, allowing considerable size and cost reduction. Converter analysis, design criteria of both power and control sections and experimental results are reported in the paper.
