Abstract
In this paper, a shunt active power filter scheme is proposed for a three phase system feeding a non-linear load. The system represents the HV generator used in high power radiology equipment. Hysteresis current control is used, which controls the operation such that a sinusoidal current is drawn from the source. The proposed method also reduces the THD, thus improving the power quality. The compensating currents are injected in phase opposition at the point of common contact to cancel out the harmonic currents in ac lines. The Hysteresis current control is used because it is simple and easy to implement. The simulation is carried out using MATLAB-SIMULINK software, whose results are displayed.
