Abstract

In this paper, a current-doubler rectifier with coupled inductors for high step-down applications is proposed. The proposed current-doubler rectifier includes two sets of coupled inductors, which can extend duty ratio to reduce the peak current through the isolation transformer and lower output current ripple. Additionally, the leakage inductors of the coupled inductors can limit current slew rate of the rectifier diodes, reducing reverse recovery loss significantly. In this study, a full-bridge phase-shift converter with the proposed rectifier, input voltage of 400V, output voltage of 12V, and full load power of 500W was built, from which experimental measurements have shown that the efficiency can reach as high as 91% under full load condition.
