| Abstract: | In order to improve the harmonic compensation performance, a novel sliding mode controller is designed to implement the reference current tracking control in three-phase three-wire shunt active power filter. The harmonic detection method based on instantaneous reactive power theory is applied and the harmonic component in load currents can be extracted quickly and exactly. The PI control technique is used to control the stability of capacitor voltage in DC side. Simulation results reveal, compared to the hysteresis controller, the designed sliding mode controller can reduce tracking error obviously and improve the harmonic compensation effect. |
