Abstract
A two-phase interleaved zero-voltage-switching (ZVS) boost converter with coupled inductors is proposed in this paper. In the proposed converter, two identical ZVS boost converters are paralleled and operate with interleaved control signals. By interleaving operation, current ripples at input and output stages are reduced. Due to the ZVS characteristic, the switching loss is significantly reduced and the efficiency is improved compared with the conventional two-phase interleaved boost converter. Steady-state analysis for the proposed converter is presented. Experimental results based on a 200 W (86V/2.33A) prototype are provided to verify the effectiveness and feasibility of the proposed converter.
