Abstract

This paper presents a novel fuzzy control scheme applied to shunt active power filters for harmonic and reactive power compensation. A TSK type fuzzy logic controller is proposed for APF reference current generation. To control the maximum switching frequency of the converter within limit a novel fuzzy hysteresis band current controller is used. The band height, based on fuzzy control principle is changed with the value of supply voltage and slope of reference current
