摘　　要：根据改进的周期平均模型，得到控制ＰＷＭ整流器交流侧相电压的参考信号，解决了间接电流控制方法在暂态过程中交流输入电流的直流偏移问题。该方法不仅具有间接电流控制方法的设计简单，控制概念清晰等优点，同时具有直接电流控制的优良的动静态性能。理论分析和实验、仿真结果完全吻合。WT5”BZ〗 According to the improved Period Average Model of PWM AC to DC voltage source converter,a new strategy of generating reference cotrol voltage for the converter is introduced in this paper. With simple parameter design and distinct control concept,the strategy not only solves the problem of ac current offset existing in conventional Phase and Amplitude Control(PAC),but keeps the dynamic and static characteristics of direct current control. Simulating and experimental results suggest that when the proposed strategy is adopted the transient wave forms of ac imput currents and dc output voltage of converter are greatly improved in comparison with those of conventional control strategies.
