Abstract

This paper deals with a comparative study between the control of three to three phase matrix converter feeding a
star-connected three phase induction machine and the control of three to three phase dual matrix converter
feeding an open-end winding induction machine. The control strategy used in both cases is based on a proposed
direct transfer function control approach of Venturini algorithm which allows to obtain a unity power factor at
the input side to boost the output phase voltage up to 150% compared to the input phase voltage, while keeping
the main advantage of the matrix converter by providing a fully bidirectional power flow operation. The main
objective of using the open-end winding topology is to ensure the minimization of the common mode voltage
which is clearly observed in the case of star-connected winding. Simulation results are presented under both
control strategies, where both matrix converters are supplied from the same three-phase power source. Whereas;
the two output voltage system of the dual matrix converter are shifted with 180 degrees. Based on the obtained
results the performances of the both control approaches are technically discussed.
