在检测电源电流和负载电压控制方式的基础上，提出了一种复合控制方式。该控制方式的指令信号通过同时检测电源电流和负载电压得到。它既具有上述两种控制方式的优点，又能克服它们各自的不足。此外，讨论了ＰＷＭ逆变器及其直流侧电压的控制方法。在此基础上研制了一台串联型ＡＰＦ实验样机，进行了相应的实验研究。结果表明，采用复合控制方式的串联型ＡＰＦ稳定性高，谐波补偿效果好。
On the basis of detecting the control mode of power supply current and load voltage, a compound control method is proposed. The command signal of this control mode is obtained by simultaneously detecting the supply current and the load voltage. It not only has the advantages of the above two control methods, but also overcomes their respective deficiencies. In addition, the control method of PWM inverter and its DC voltage is discussed. On this basis, a tandem APF experimental prototype has been developed and corresponding experimental studies have been carried out. The results show that the tandem APF with compound control method has high stability and good harmonic compensation effect.
