A novel SVM-based hysteresis current controller

摘要

In this paper, a novel space vector modulation (SVM)-basednhysteresis current controller (HCC) for squirrel cage induction motorsnis proposed. This technique utilizes all advantages of the HCC and SVMntechnique. The controller determines a set of space vectors from anregion detector and applies a space vector selected according to thenmain HCC. A set of space vectors including the zero vector to reduce thennumber of switchings is determined from the sign of the output frequencynand output signals of three comparators with a little larger hysteresisnband than that of the main HCC. A simple hardware implementation isnproposed and experimental results of the SVM-based HCC are also shown
