SVM-based hysteresis current controller for three-phase PWM rectifier

A space vector modulation (SVM) based hysteresis current controller (HCC) f or the pulse width modulated rectifier is proposed. The proposed technique utilises all the advantages of the HCC and SVM techniques. The controller d etermines a set of space vectors from a region detector and applies a space vector, selected according to the HCC. A set of space vectors, including t he zero vector to reduce the number of switching, is determined from the ou tput signals of three comparators. A simple hardware implementation is prop osed, and experimental results of the SVM-based HCC are shown.
