A resonant current control of an open-end winding induction motor fed by an indirect matrix converter

An open-end winding induction motor fed by a two-output stages Indirect Matrix Converter (IMC) is presented. The capability of the IMC input stage to produce different DC voltage levels is exploited. The IMC output stages commutates at reduced DC voltage when the output voltage requirement is low. Furthermore, the modulation strategy for the output inverters aims to reduce the common-mode voltage and compensate the zero sequence currents in the load. To ensure a good tracking of the machine currents, a Resonant Controller (RC) is used. Simulation results showing the performance of the control scheme and the reduction of common-mode voltage are presented using a PSim/Matlab simulation platform.
