摘要
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。
In this paper,a hybrid control approach is proposed based on the control approaches of detecting source current and load voltage.The reference signal in this control approach is obtained by detecting both source current and load voltage.Thus,it combines their advantages and at the same time,overcomes their respective drawbacks.In addition,the control methods of PWM inverter and its dc side voltage are discussed.On the basis of them,a prototype of the series active power filter is manufactured and corresponding experiment studies are made.The results show that the performance of the series active power filter will be improved when adopting the hybrid control approach.
