Abstract : This paper analyzes two dual-motor fault-tolerant topologies for aerospace thruster application.
The first structure supplies independently both machines while the second one connects them in series for reducing the number of transistors and offering a capability of energy management between the sources.
Inverter short-circuit fault is considered.
Based on the peak-currents obtained in simulation in degraded mode without reconfiguration and with two different reconfiguration strategies, the two proposed topologies can be compared in economic and technical aspects.


Keywords : multiphase machines series connected fault-tolerance open-winding dual-drives short-circuit fault dual-motor aerospace
