一种三电平逆变器驱动六相永磁同步电机的在线开路故障诊断技术

This article presents an online open-phase and open-switch fault diagnosis technique for three-level (3L) active-neutral-point-clamped (ANPC) inverter-fed six-phase permanent-magnet synchronous machine (PMSM) drives with one or two isolated neutral points. One of the main advantages of six-phase PMSM drives is their intrinsic capability to operate at a lower power level in the event of phase or po...
