Summary:针对电力系统传统通信电源设备功率因数低，电源谐波高的不足，提出一种新型的无桥Boost PFC电路结构。通过对电路拓扑结构的工作原理分析，应用平均电流控制策略，建立了相应的仿真模型。仿真结果表明，与传统的Boost PFC相比，无桥Boost PFC电路能够很好地提高功率因数，抑制电流谐波，且输入电流能很好地跟踪输入电压。最后设计了一台500W的实验样机，实验结果验证了所提出电路的正确性和可行性。
Bibliography: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.
