Hysteresis Current Control Technique Based on Space Vector Modulation for Active Power Filter

In this paper, the hysteresis current control (HCC) technique based on space vector modulation (SVM) for active power filter (APF) is proposed. The switching control algorithms of the HCC based SVM manage to generate compensated current according to the reference current. Harmonics extraction is calculated for the power compensation based on the instantaneous active and reactive power theorem in time domain. A closed loop control system is carried out and the APF manages to generate better compensated harmonics currents to the power grid.
