A Fault Tolerant Operating System in a Doubly Fed Induction Machine Under Inverter Short-circuit Faults

This paper presents an original strategy of fault tolerant operating in case of doubly fed induction machine (DFIM). The considered fault is short-circuit of inverters leg (T1 and T2). The proposed strategy permits the reconfiguration management of both inverter topology and DFIM field oriented control. Consequently, the drive continuous operation is guaranteed in the presence of the damaged inverter. Simulation results are presented to emphasize the effectiveness of the proposed method
