摘要：
This paper discusses a distributed electric propulsion (DEP) system for virtual aviation systems. The DEP system includes six propulsion inverters with SiC MOSFET modules. Through three different virtual flight profiles normal planed one, another with changed trajectory, and the other with changed trajectory and failure mode power and current sharing between these modules was investigated. Measurement-based loss simulations and thermal simulations, with defined cooling conditions, were performed to test power redundancy and loss in each propulsion inverter for all the three virtual profiles.
