Abstract: Shunt Active power filters have been proved as useful elements to correct distorted currents caused by non-linear loads in power distribution systems. This paper deals with a Novel Adaptive Hysteresis Band Current Controller, a new control scheme for an Shunt Active Power Filter (APF) to reduce harmonics and to compensate the reactive power of three-phase rectifier. The switching dynamics of a voltage source inverter (VSI) Four pole based three-phase, four-wire shunt APF system with adaptive hysteresis band current control has been studied and verified by simulation. The simulation results of Active Power Filter (APF) control technique, carried out in MATLAB environment, are presented in this paper and are quite satisfactory to reduce harmonics and reactive power components from utility current.

Index terms: Active Power Filter (APF), d-q-0 reference frame, and adaptive hysteresis band current controller.
