N2 - When dealing with open-circuit faults in a five-phase permanent magnet synchronous motor (PMSM) supplied by a current-source inverter (CSI), existing fault-tolerant methods typically assume that both the upper and lower semiconductor switches of the faulty inverter arms are open-circuited simultaneously. However, in a faulty inverter arm, the open-circuit fault may only occur on the upper or lower semiconductor switch, and this issue has not been investigated. Therefore, this paper proposes a fault-tolerant method based on modified space-vector pulse-width modulation (SVPWM) for a five-phase PMSM supplied by CSI when the open-circuit faulty semiconductor switches are distributed across three arms of the CSI. Experimental results have confirmed the effectiveness of the proposed method.
