摘　　要：建立单相半桥整流器在D-Q坐标系下的状态空间平均模型,用延迟的方法可得到输入电流的D-Q分量,实现此模型的单相PFC控制。通过对模型的分析,利用MATLAB对PWM调制方式控制系统进行仿真,获得了高精度电流跟踪误差和较好的电压响应。The average state model of the single-phase half-bridge rectifier was built in the D-Q coordinate system, and the D-Q elements of the input current were got with delay, so single-phase PFC control of the model was realized. After analyzed the model, control system with WPM modulation mode was emulated by MATLAB, and higher tracking error of current and better voltage response was achieved.
