A Current Source Active Power Filter Controlled by a Sliding Mode Approach

In this paper presents a current source active power filter controlled by a sliding mode approach is presented. The proposed control method is fast and robust and uses the sliding mode technique to generate alphabeta space-vector modulation. This allows forcing the input line currents to track the desired reference. With this control strategy the input currents of the active power filter are actively shaped, being possible to maintain the desired currents even with high ripple DC inductor current. Simulation results are presented and discussed. The obtained results show the effectiveness of the proposed control method
