High order Sliding Mode Control for shunt Active Power Filter

The aim of this paper is to present the implementation of a shunt Active Power Filter (APF) to reduce the harmonic distortion in the current of a voltage node feeding a nonlinear load. A two-level three-phase Voltage Source Inverter (VSI) is used for the APF. The control methodology employed is based on a high order sliding mode algorithm known as Super-Twisting. Simulation results are presented that confirms validity of the proposal.
