In this paper three phase shunt active filter (SAF) is used to reduction of harmonics in three phase four wire system. The shunt active filter is commonly three independent current controlled voltage source inverter (VSI) with common DC link capacitor. The synchronous reference frame theory (d-q Theory) is used for extracting compensated reference current and Fuzzy Logic Controller (FLC) is used to reduction of load current harmonics. The triggering of gate pulses by using PWM controller and applied to three phase SAF.
