A fault tolerant strategy is proposed to control the power flow in High-Speed Permanent Magnet Machines (HS-PMM) with arbitrary Electromotive Force (EMF) waveform. The strategy aims to minimize ripple torque and reduce reactive power that flow on the machine. The control algorithm is based on the instantaneous reactive power theory and is implemented with a conventional three-phase four-wire converter. The focus of the work emphasizes the Fault Detection Algorithm (FDA), which is key to the correct performance of the fault tolerant system. Simulation results are presented to the system when an open circuit fault occurs and the correct performance of the FDA and the entire system is observed. Keywords? High-Speed PMM, Fault Detection Algorithm, Fault Tolerance.
