The pq-Theory is equally applicable to any generous voltage and current waveform. So it is equally applicable to linear as well as nonlinear system. For linear system, pq-Theory gives similar results as given by conventional theory. Simulation results are presented under steady state conditions and performance of shunt active filter is compared with two different Voltage Source Inverter used (Three Level- & Five Level Inverter). The controlling of Shunt Active Filter becomes difficult if the supply voltage is non sinusoidal. Under sinusoidal supply voltage Shunt Active Filter can satisfy the three characteristics of power system – sinusoidal source current, constant instantaneous power and unity source power factor. But under non sinusoidal supply voltage one will have to be satisfied with one of the three characteristics. Based on this three compensation techniques were formed.
