A space vector modulation based hysteresis current controller for the PWM rectifier with voltage link

A space vector modulation (SVM) based hysteresis current controller (HCC) f or the PWM rectifier is proposed. This technique utilizes all advantages of the HCC and SVM technique. The controller determines a set of state space vectors from a region detector and applies a space vector selected accordin g to the HCC. A set of state space vectors including the zero vector to red uce 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 also shown.
