Fine-tuning of the active filtering techniques have always been the focus of many researchers in the area of active power filters for proper power quality mitigation in retrofit systems. In this paper, the newly proposed Icosφ algorithm is applied to a three-phase shunt active filter to provide harmonics' and reactive power compensation as demanded by the non-linear reactive load. The design is verified in simulation as well as implemented in hardware using simple analog circuits and results are compared.
