Over the past few years, the enormous increase in the use of non-linear loads, arises many power quality issues like high current harmonics, voltage distortion and low power factor etc. on electrical grid [1]. Hence the proliferation of non-linear load in system generates harmonic currents injecting into the AC power lines. This distorted supply voltage and current causes malfunction of some protection devices, burning of transformers and motors, overheating of cables. Hence it is most important to install compensating devices for the compensation of harmonic currents and voltages produced due to nonlinear load. The degradation in power quality causes adverse economic impact on the utilities and customers. Harmonics in current and voltage are one of the most commonly known power quality issues and are solved by the use of hybrid series active power filter (HSAPF). In this paper, a new controller design using sliding mode controller-2 is proposed to make the HSAPF more robust and stable. An accurate averaged model of three-phase HSAPF is also derived in this paper. The design concept of the robust HSAPF has been verified through simulation and experimental studies and the results obtained are discussed.
