Fuzzy Logic Controller Based Variable Hysteresis Band in Three-Phase Shunt Active Filter
Harmonic distortion is a form of electrical noise. It is a superposition of signals, which are of multiples of fundamental frequency. Proliferation of large power electronic systems results in increased harmonic distortion. Harmonic distortion results in reduction of power quality and system stability. The shunt active power filter has proved to be a useful device to eliminate harmonic currents and to compensate reactive power for linear/nonlinear loads. This paper presents the optimization of shunt active power filter parameters based on fuzzy logic control. The novel adaptive hysteresis band current controller changes the hysteresis bandwidth according to modulation frequency, supply voltage, DC capacitor voltage and slope of the reference compensator current wave. The results of the computer simulation prove that the injected harmonics are greatly reduced; system efficiency and power factor are improved.
