Abstract:This paper introduces the active power filter model of rotating d-q reference frame. PI controller is analyzed based on this model carefully. The active power filter reference current is far from DC signal, so the PI controller can’t obtain zero steady-state error. In this paper, a current control method based on PI and resonant controller is proposed. Resonant controller can obtain zero steady-state error for sinusoidal inputs with the same frequency as its resonant frequency. So, proposed current control scheme can compensate specified harmonics with zero steady-state error. Harmonics compensation performance can be improved for the active power filter.
