Improvement of power quality using PQ-theory shunt-active power filter

This paper deals with the staging the evaluation of a three-phase Shunt APFS for Power Quality improvement. Power Quality complications can be take up using SAPFS. A simulation model of the three-phase shunt active filter had been implemented based on the mathematical modelling of the system where we can observe the considerable improvement in the source current in the norms of Total Harmonic distortion (THD) of source current. We can also observe the correction in the power factor (PFC). Properties are restored in the terms of source voltage and source current are in phase by this implementation.
