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

Abstract

A space vector modulation (SVM) based hysteresis current controller (HCC) for the pulse width modulated rectifier is proposed. The proposed technique utilises all the advantages of the HCC and SVM techniques. The controller determines 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 the zero vector to reduce the number of switchings, is determined from the output signals of three comparators. A simple hardware implementation is proposed, and experimental results of the SVM-based HCC are shown.
