Hardware implementation of series hybrid active power filter using a novel control strategy based on generalised instantaneous power theory

In the area of power quality conditioners, the series hybrid active power filter (SHAPF) has been focused more in recent times because of its multi‐functionality and lower inverter rating requirement. Existing control strategies for SHAPF are based on extracting either source current harmonics or load voltage harmonics. In this study, a novel control scheme based on decomposing multiphase voltage vector into different vectors that represent different components of power is proposed for SHAPF. The mathematical formulation of the proposed control scheme with its applications to SHAPF is presented. The validity of the proposed control scheme is verified by simulation as well as experimental study.
