| 摘 要： | 有源滤波器中电感值对系统的滤波效果起决定性的作用。如果电感值太大，则系统不能实时跟踪指令电流信号。反之如果太小，则补偿后的纹波电流过大。从跟踪基波出发，推导出并联型有源电力滤波器输出电感值的估算公式。并通过对三相整流负载的补偿性能分析，验证了该公式的正确性。采用本方法选取的电感值。可以使补偿电流纹波较小，并且能得到良好的跟踪补偿性能。

| Abstract: | Inductance value of active power filter determines the system's performance. The filter will he not able to track the signal of instruction current in real time if the inductance value is too excessive. On the contary, the ripple of compensation current will be superfluous if the inductance value is too small. A formula to estimate the inductance value of a parallel active power filter on the basis of the fundamental wave is found. The rationality of this formula is proven by analyzing the compensation performance of three phase rectifier load. Inductance value selected by this method can minish the ripple of compensation current and get good compensation performance. |
