Abstract

A new full-wave rectifier is proposed in this paper. By integrating the proposed rectifier with a classic current-fed converter as an example, a dual-inductor boost converter with ripple cancellation is presented. It has several features, such as high voltage gain with smaller transformer turns ratio, recovery of the transformer secondary leakage energy, low voltage stress on the rectifier diodes, and nonpulsating input and output currents. These properties make it desirable for high-frequency high-efficiency high-voltage-gain applications, such as the renewable energy source power system. In addition to the circuit analysis and design, a 150-kHz 24-36-V-input 200-V/600-W-output converter prototype is implemented and tested to demonstrate its feasibility.
