Abstract

In this paper a step-down ZVS power converter with a self-driven synchronous rectifier (SDSR) for a low-voltage high-current applications is proposed. A transformer leakage inductance, a resonant capacitor and a diode make up the active resonant network. To improve the performance of the converter, a SDSR with a center-tapped transformer is used at the secondary side of the converter. Consequently, due to transformer leakage inductance in secondary side, the output section requires no additional inductor, leading to a major size reduction of the circuit. For verification purposes, a laboratory prototype of the proposed converter is manufactured. Experimental results are presented for waveforms to validate the theoretical outcomes.
