Open-End Winding Induction Machine Fed by a Dual-Output Indirect Matrix Converter [PDF]
IEEE Transactions on Industrial Electronics, 2016 [EN] Open-ended winding induction machines fed from standard two-level voltage source inverters (VSIs) provide an attractive arrangement for ac drives. An alternative approach is to use a dual-output indirect matrix converter (IMC). It is well known that the IMC provides fully bidirectional power flow operation, with small input size filter ...

Indirect matrix converter modulation strategies for open-end winding induction machine [PDF]
IEEE Latin America Transactions, 2014 [EN] 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.
