ABSTRACT
This paper proposes a transformerless hybrid series active filter which is connected to a single phase distribution feeder. This system uses a sliding mode controller and filtering techniques to reduce voltage and current harmonics for a typical nonlinear load (VSC). The reactive power compensation is done by injecting sag, swell, and distortions at grid side of Point Common Coupling (PCC). In the existing methods to compensate harmonics, PI controllers were to control DC link voltage, there maybe presence of some amount of steady state error and also this PI controller may not work under continuous condition mode. So the authors have opted for Fuzzy Logic Controller (FLC) technique to improve steady state error and the system performance should be improved by reducing the harmonics. Both the existing PI based and fuzzy based controllers’ results are compared and are shown on Matlab/simulink.
