The method proposed compensate non linear load by improving the power factor to the desired value and also eliminate the harmonics under distorted Source voltage and source currents. A detailed synchronization circuit is presented for proper sequence of operation of the shunt active power filter. The active power filter (compensator) is realized using a single-phase voltage source inverter operated in a PWM hysteresis current control mode. The method is validated through simulation results using MATLAB. The results have been shown with ideal and practical compensator with an emphasis on dynamic performance.
