Abstract
A zero-voltage-switching (ZVS) Cuk converter with low input current ripple is proposed in this paper. This converter consists of a coupled inductor, an auxiliary serial inductor, a capacitor, and two power switches. Two separate inductors in the conventional Cuk converter are replaced with a coupled inductor. The coupled inductor in the proposed converter provides not only an input current with very low current ripple but also ZVS operation for both main and auxiliary switches. Due to ZVS operation of power switches, switching losses are significantly reduced and the efficiency is improved. The operation principle and steady-state analysis of the proposed converter are provided in detail. A prototype of the proposed converter is developed, and its experimental results are presented for validation.
