• Multiphase motors are being used in high power electric transportation applications owing to their advantage such as high reliability, efficiency and fault-tolerant capability. A high power density drive system is needed to reduce the losses and increase heat-sinking capability. In this paper, the power drive module is packed using Silicon Carbide (SiC) MOSFET devices as they are capable of operating at high voltage, high frequencies and low reverse recovery current. The impact of SiC module on the performance and efficiency of a multiphase drive system for fault-tolerant applications is evaluated and tested in the platform of 120kW multi-phase permanent magnet (PM) motor with different operating conditions. The results show that the dynamic performance and efficiency of the power drive are significantly improved based on the SiC MOSFET devices.
