| 摘 要： | 开关功率器件长时间运行的不稳定及定子绕组断路故障，限制了内部永磁同步电机在高可靠性驱动领域中的应用．提出了一种具有容错功能的驱动控制系统，在三相三桥臂逆变器的基础上，新增加一个桥臂，使之在故障发生后与星型连接的永磁同步电机的中性电线相连，在电机内部仍能形成圆形旋转磁场，建立了驱动控制仿真模型．

| Abstract: | Interior Permanent Magnet Synchronous Motor （ IPMSM ） is restricted in the high-reliability applications because of the switching power devices instability for a long time to run and the stator winding circuit failure. An innovative fault-remedial control strategy is proposed, which can offer a new fourth inverter pole based on three-phase three-bridge inverter, to connect the neutral point of the motor when the failure occurs. Then it can also form a circular rotating magnetic field. The topologic driver control model by the software of Matlab is simulated. |
