摘　　要：针对电力电子整流电路需要校正功率因数的情况,以传统标准无桥PFC电路模型为基础,设计一种电容改善型无桥PFC电路。分析了电路的工作模态,对电路精确建模并设计一种相应的闭环控制参数设计方法,通过MATLAB/Simulink对电路进行仿真和试验验证。In view of the situation that the power electronics rectifier circuit needs to correct the power factor,a capacitor improvement bridgeless PFC circuit was designed based on the traditional standard bridgeless PFC circuit.The working modes of the circuit were analyzed in detail in this paper.The circuit was modeled accurately and closed-loop control parameter design method was designed.The circuit was simulated by MATLAB/Simulink and verified by experiment.
