FAULT-TOLERANT CONTROL FOR OPEN-END STATOR WINDING INDUCTION MACHINE SUPPLIED BY TWO THREE PHASE CASCADED INVERTERS WITH ONE FAILED INVERTER

Abstract

In this paper the authors propose the degraded mode operation of the open-end stator winding induction machine supplied by two converters on three levels. Each converter is constituted by two three-phase inverters in cascaded. The different conditions that must be respected for the operation mode will be presented.
