Power Quality is a major area of concern for industrial as well as domestic loads. Thus power electronics has proved as a major field in the area of power quality improvement. Active Power Filters are implemented on a wide scale where voltage as well as current compensation is required. The active filtering is that it automatically adapts to changes in the network and load fluctuations. They can compensate for several harmonic orders, and are not affected by major changes in network characteristics, eliminating the risk of resonance between the filter and network impedance. The shunt active filter for reducing the current harmonics, increasing the power factor and voltage profile. Here the current reference required by the voltage source inverter is the use of the instantaneous reactive power theory. By this method we take reference current and voltage and match with actual current and reduced the error by current controller then gives the opposite with same magnitude of current harmonics to the system.
