Abstract

Active power filter (APF) has been proved as effective means to compensate distorted and reactive currents caused by nonlinear loads. Proportion-Integral (PI) can not get zero steady-state error of output current due to its bandwidth limitation. A novel current control architecture in the synchronous rotating frame with ordinary PI and repetitive controller with feedforward is proposed to improve the compensation accuracy. Detailed theory analysis of the proposed control technique is also showed. At last, the improvement of compensation accuracy is verified by not only simulation results but also experimental results. The influence of the subharmonic is also inhibited effectively.
