Abstract

This paper presents a shunt single phase active power filter (APF) for harmonic and reactive power compensation. A simple method, using sampling and integration has been proposed for APF reference current generation. This method simplifies the calculation algorithm. A high performance adaptive hysteresis band current controller tracks the reference current. It changes the hysteresis bandwidth according to the modulation frequency, supply voltage, DC bus voltage and slope of reference current. MATLAB/SIMULINK model has been presented. Responses of the simulated model show that harmonic and reactive components of load current are completely eliminated from supply current.
