AN IMPROVED SPACE-VECTOR-BASED HYSTERESIS CURRENT CONTROLLER

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.
