Abstract

In order to reduce the current harmonics caused by the widely used non-linear load such as a diode rectifier, a series connected active power filter (APF) can be applied. Compared with the conventional uniform harmonic resistance (UHR) control strategy, a novel selective harmonic resistance (SHR) control method is proposed to improve the compensation performance. In the SHR control, the series APF will provide larger resistance to certain order current harmonics with higher quantity. Also, the proposed SHR control can improve the system stability. Simulation and experiment results verified the improved compensation performance of the SHR control in comparison to UHR control.
