Nowadays, the extreme use of power electronic device and other non-linear load introduce the problem of power quality deterioration in voltage and current waveforms. Passive filters are used widely to solve this problem owning to their simplicity in operation and low cost. But they face the major drawback of its dependency of performance on the system parameters as well as resonance problem. Active Shunt Filter(ASF) are widely used to overcome these problem. This paper presents Active Shunt Filter comprising of Instantaneous real and reactive power(p-q) theory for Power Quality Improvement. Hysteresis current controller is used for PWM pulse generation for VSI. The simulation is carried out in MATLAB/SIMULINK and results indicate the effectiveness of Active Shunt Filter for reduction of harmonics(THD) up to permissible limit as specified by IEEE 519 and reactive power compensation.
