Abstract
An isolated Zero-Voltage-Switching (ZVS) buck converter based on full-bridge topology is proposed in this paper. In the proposed converter, a clamping capacitor is across the second bridge switches to reset the isolation transformer and provide ZVS features to power switches. By interleaving operation, current ripples at input and output stages are reduced. Due to the ZVS characteristic of power switches, the switching loss is significantly reduced and the efficiency is improved compared with the conventional full-bridge buck converter. Steady-state analysis for the proposed converter is presented. Experimental results based on a prototype are provided to verify the effectiveness and feasibility of the proposed converter.
