Abstract

This paper presents a method for the harmonic and the reactive power compensation with an adaptive hysteresis band current controller and a control algorithm for hybrid shunt active power filter (HSAPF) to eliminate the harmonic and compensate the reactive power in three-phase thyristor bridge rectifier. The adaptive hysteresis band current controller can change the hysteresis bandwidth according to modulation frequency, supply voltage, dc capacitor voltage and slope of the  u_i(i=a,b,c) reference compensator current wave. Until now, all of the studies have been carried out through detail digital dynamic simulation with the MATLAB Simulink Power System Toolbox. The results of simulation study of the new HSAPF control technique and algorithm presented in this paper certificate this kind of APF has perfect harmonics compensation characteristics in utility current.
