There are many factors that affect the performance of active power filter, which is a key factor for command current tracking control. Aiming at the deficiency of traditional PR controller, this paper puts forward an improved PR controller-vector resonant controller. The controller has the advantages of stronger anti-interference ability and greater gain at the resonance point, and it can improve the accuracy of harmonic compensation in the current compensation control. In this paper, the
