Active power filters are widely used for the reduction of harmonics in the power system caused by nonlinear loads. The Shunt Active Power Filter (SAPF) injects a suitable compensating current at a point of the line known as the point of common coupling (PCC) so that the harmonics present in the line are cancelled out and the sinusoidal nature of voltage and current waveforms are restored. A thr...
