In this paper, a novel space-vector-modulation (SVM)-based hysteresis
current controller (HCC) is proposed. This technique utilizes all adva
ntages of the HCC and SVM technique. The controller determines a set o
f space vectors from a region detector and applies a space vector sele
cted according to the main HCC. A set of space vectors including the z
ero vector to reduce the number of switchings is determined from the s
ign of the output frequency and output signals of three comparators wi
th a little larger hysteresis band than that of the main HCC. A simple
hardware implementation is proposed, and experimental results of the
SVM-based HCC are also shown.
