In last few decades power quality improvement has been major research topic. This is due to wide use of semiconductor and non-linear devices. The power quality of any source is measured by some indexes set by internationally such harmonics factor, and telephonic interference level etc. Employing several harmonic compensation methods. We are able to meet those index limits set by international bodies. This is very essential in reference to performance & economy of operation. Power filters are extensively employed in modern electrical power distribution system to remove harmonics associated with the system. Shunt active power filter (SAPF) is one of the power filters which have better dynamic performance. SAPF required accurate control technique which provides robust performance under source & load unbalance. Control methods are responsible for generating reference currents which is employed to trigger Voltage Source Inverter. Hence, compensation of harmonics depends largely on technique used. For any Shunt APF system there is many way of implementing control blocks whose output is given to gate of the voltage source inverter.
