Abstract
The paper describes and compares the application of fuzzy logic controller and proportional controller to a three phase shunt active power filter used to compensate harmonic current and reactive power of nonlinear loads simultaneously.
The proposed scheme uses a pulse width modulation (PWM) technique to generate the switching signals to the active filter, p-q theory for harmonic current identification and fuzzy logic and P controllers for active filter current and DC capacitor voltage control. The performance of fuzzy logic controller is compared with a conventional P controller. The dynamic behavior of fuzzy logic controller is found to be better than the conventional P controller.
