چکیده
9 www.alliedjournals.com Abstract— Power quality is a very important issue. Non-linear loads and semi-conductor devices connected to AC electric mains generate unwanted signals (harmonics) in the dynamics of current which are responsible for additional power losses in heat loss and the risk of equipment damage or malfunctioning. In the simulink model of shunt active filter fuzzy logic controller and hysteresis current controller for reducing the harmonic distortion. Powergui tool of mat lab provides the function of FFT analysis which is very important to calculate total harmonic distortion in source current. By taking various firing angles the total harmonic distortion is calculated by FFT analysis.
