通过为三冗余3×3相永磁辅助同步磁阻电机创建零序电流路径实现有效的匝间短路故障缓解

Effective mitigation of excessive stator turn fault current is crucial for fault tolerant machine drives. In this paper, a simple and effective method is proposed for a triple redundant 3 × 3-phase permanent magnet-assisted synchronous reluctance machine by using three 3-phase 4-leg inverters. The fourth leg creates a zero sequence current path when a terminal short circuit is applied in an event ...
