Digital Implementation of Fuzzy Control Algorithm for Shunt Active Filter

摘要

The paper deals with a digital-signal-processor (DSP)-based implementation of a Fuzzy control algorithm for a three-phase active filter (AF). The laboratory prototype model of the AF uses voltage source inverter (VSI) with pulse-width modulation (PWM) current control technique. The AF is employed to compensate harmonics and reactive power of a non-linear load.
