一种用于三相有源电力滤波器的复合PI控制器并联电流电压控制策略

The conventional control strategy for active power filters (APFs) is essentially a nested structure, where the output of the outer voltage loop will affect the command current of the inner loop, inevitably impairing the performance in harmonic compensation. In this article, to enhance the harmonic-compensation performance, the output of the dc-link voltage loop has been modified and added as a dis...
