逆变器开路故障对永磁同步电机多物理量的影响

The fault of the drive system mainly occurs in the power transistor of the inverter. Compared with the short-circuit fault, open-circuit fault is not easy to perceive and accurately detect, and it will not cause instantaneously devastating damage to the system. In the case of the open-circuit fault, the motor will be in limp operation mode. At present, most of the research results are focused on f...
