Abstract

Five-phase machines represent a widely adopted choice for fault-tolerant applications due to their extra degrees of freedom. The paper deals with the single-phase short-circuit (SC) fault tolerant control using original transformation matrix (OTM) for five-phase permanent-magnet (PM) machines. The proposed method firstly follows the fundamental phase current injection (FCI) method based on the calculated SC current. Moreover, third-order harmonic phase current injection (THCI) method is presented to reduce copper loss. The computational method of derating factor is also adopted for industrial applications. The fault tolerance and dynamic performance are also verified by the experimental results. A reduction of copper loss in THCI method by about 15% is achieved, compared with general and FCI methods.
