Abstract :
A fault-tolerant control strategy of open-end winding permanent magnet synchronous motors fed by cascaded two-level inverters is proposed in this paper. When an open-circuit fault occurs on switches of the inverter, the motor will stop if the control strategy will not be changed. By means of reconfiguring the topology into two-phase H-bridge inverter, and adjusting the control strategy to two-phase vector control, the motor drive system can operate in two-phase mode. Simulation and experimental results validate the proposed scheme.
