In this paper, an improved space-vector-based hysteresis current contr
oller (SVBHCC) is proposed. The controller determines a set of space v
ectors from a region detector and applies a spare voltage vector selec
ted according to the main HCC, A set of spade vectors including the ze
ro voltage vector to reduce the number of switchings is determined fro
m the information of the current errors, which are wider than those of
the main HCC, A simple hardware implementation is proposed and the go
od experimental results of the SVBHCC are also shown.
