Abstract


This paper describes a shunt active power filter for compensating harmonic currents and reactive power. The shunt active power filter(SAPF) was implemented with a phase pulse modulated current control voltage source inverter. The proposed system is based on PLL synchronization with reduced fuzzy logic controller (RD-FLC). These control techniques for SAPF prove that source current is sinusoidal even when load is non linear. The CC-VSI inverter switching is done according to gating pulse obtained from the hysteresis controller using RD-FLC controller. The proposed system is investigated using simulation results. The effectiveness of the controller is observed in the form of total harmonic distortion, reactive power compensation and settling time of dc link voltage under non linear load condition. This technology reduced the rules of fuzzy logic controller from 49 to 37.
