In this paper an Indirect Matrix Converter (IMC) topology suitable for controlling an open-end winding induction machine is presented. The IMC is a direct power converter having no bulky energy storage elements with an input or current rectifying stage and a voltage source inverter as an output stage. To provide energy to an open-end winding induction machine two output stages are needed. Then, it is possible to obtain a voltage across any phase of the load up to 1.5 times the input phase voltage without overmodulation. Two pulse width modulation strategies are presented: the first one is based on space vector modulation that suppresses the zero sequence voltage in the load whereas the second one is a carrier-based modulation which generates lower distorted input converter currents. Results are presented and discussed.
