一种无需分压电容、辅助桥臂或双向可控硅的创新型容错三相表贴式永磁同步电机驱动器

The existing fault-tolerant three-phase ac drives need split capacitors, auxiliary legs, and triode for alternating current (TRIACs) upon a standard three-phase two-level voltage source inverter (VSI) to obtain the self-healing ability toward open-phase faults (OPFs). In order to reduce the cost, volume, and weight, this article proposes a novel fault-tolerant three-phase surfacemounted permanent ...
