Abstract
In this study, a new substantial improvement of the hysteresis current control technique is proposed for shunt active power filter to eliminate harmonics and to compensate the reactive power of three-phase rectifier. A simple and fast prediction of the hysteresis band is added to a phase-locked-loop control, in order to ensure constant switching frequency and tight control of the position of modulation pulses. This allows high accuracy in tracking highly distorted current waveforms and minimises the ripple in three-phase systems. This technique is very simple and robust, its implementation employs a small number of conventional, inexpensive analog and logic components. The proposed technique determines the switching signals of the three-phase shunt active power filter and an algorithm based on the dc bus capacitors voltage regulation using Proportional-Integral (PI) is proposed to determine the suitable current reference signals. The behavior of the proposed technique has been fully verified by simulation using MATLAB/SIMULINK.
