The paper presents a repetitive-based controller for a three-phase three-wire shunt active filter aimed to compensate reactive power and harmonic distortion in the case of distorted and unbalanced source voltages and load currents. The repetitive scheme used here is aimed to compensate specifically the harmonics 6 k plusmn 1 (k = 0,1,2,...,infin ) of the fundamental frequency. The scheme includes a damping gain to somehow limit the infinite gain produced, also a simple low pass filter (LPF) is… CONTINUE READING
