Comprehensive Review of Fault-Tolerant AC Machine Drive Topologies: Inverter, Control, and Electric Machine

초록

Fault-tolerant operation capability has become important in AC machine drives as their applications are rapidly expanding towards transportation, renewable energy generation, and transmission. A number of fault-tolerant AC machine drives have been proposed and investigated over the past decades, and this paper comprehensively reviews the relevant technologies. Since the required level of post-fault drive performance is highly dependent on the application, this paper first attempts to provide a clear definition of fault-tolerance in AC machine drives. This new definition is used to evaluate AC machine drive topologies that have been proposed to provide fault-tolerant operation in one or several motor drive components failure. The comprehensive review of AC machine drives includes inverter topologies, control techniques, and electric machine designs.
