Abstract :
This paper presents a new and efficient control scheme which adopted the voltage source inverter to decrease current harmonics generated by the nonlinear load. The sliding mode control is used in the current control loop to achieve fast dynamics and a simple proportional-integral controller is adopted in the outer voltage control loop to achieve slow dynamics. The proposed scheme implements simplified control algorithms based on direct current control (DCC) and indirect current control (ICC) for designing trajectories in sliding mode control based shunt active power filter (SAPF). The performances of the DCC and ICC techniques were verified through a simulation with MATLAB. Simulation results confirm that compared to the conventional DCC scheme, the ICC scheme using sliding mode control can achieve high power factor and current harmonics elimination in SAPF.
