摘要
A novel implementation of a high power factor boost converter with increased efficiency is described. In this converter, a new zero-voltage transition technique is used for soft switching of the main and auxiliary switches; also, no additional voltage and current stresses on the main and auxiliary switches occur. The operating modes, theoretical analysis, and design considerations of the proposed converter are explained in detail. To evaluate the performance of the proposed converter, simulation and experimental results for a 400-V, 50-kHz, 0.5-kW prototype AC-DC power factor correction converter is presented. Finally the simulation and experimental results are given to verify its rationality and practicability.
