Abstract

A zero-voltage-switching (ZVS) voltage doubled single-ended primary inductor converter (SEPIC) is presented in this paper. An active clamp circuit is added to the conventional isolated SEPIC converter to clamp the voltage across the switches and provide ZVS operation. Voltage doubler is adopted as an output stage to provide high voltage gain and confine the voltage stress of output diodes to the output voltage. Moreover, the reverse-recovery problem of the output diodes is alleviated due to the leakage inductance of the transformer. This converter besides an electrical isolation provides higher efficiency due to soft-switching commutations of the power semiconductor devices. The operation principle and steady-state analysis of the proposed converter are provided. A prototype of the proposed converter is developed, and its experimental results are presented for validation.
