Abstract : This paper analyzes two dual-motor fault-tolerant topologies. The first one supplies independently both machines while the second one connects them in series for reducing the number of transistors. For a given DC-link voltage, the converter component sizing is based on the peak current obtained in the normal and degraded modes.

Keywords : Aerospace Multiphase drive Open-winding Fault tolerance Inverter dimensioning TVC system Multi-machine system Series connected
