一种基于新型无桥 Boost PFC 的通信电源 AC/DC 变换器设计
Design of AC/DC converter in telecom power supply based on bridgeless Boost PFC
摘要
Abstract
The traditional communication power supply equipment in electrical power system has the shortcoming of low power factor and high current harmonics, so a new bridgeless Boost PFC circuit construction is proposed. The corresponding simulation model is built by analyzing the topology structure of the circuit and adopting average current control strategy. Simulation results show that bridgeless Boost PFC can provide a high power factor and can restrain current harmonics, and the input current can keep track of the input voltage waveform well. Finally a 500 W prototype is designed. The simulation and experiment results verify the correctness and feasibility of the proposed topology. <br> This work is supported by National Natural Science Foundation of China (No. 61105030).关键词
