Fuzzy logic controller for shunt Active Power Filter

This paper presents a shunt Active Power Filter (APF) based on detection load current and harmonic voltage at the point of installation by using the fuzzy control method. The fuzzy logic based PWM technique will reduce harmonics and compensate reactive power. The shunt APF is implemented with PWM-current controlled Voltage Source Inverter (VSI) and the switching patterns are generated through a fuzzy logic control. The simulation results are performed to verify the validity and effectiveness of the shunt active filter equipped with the fuzzy logic control.
