Digital Twin for a 10 MW Electrical Drive System for Future Electric Aircraft Applications

Reliable and high power density electric machine and inverter solutions are essential for a variety of applications. Digital twin for future electric aircraft applications can contribute to analyze the system behavior and the effects between the fast-switching inverter and the electric machine. Within this paper, the concept of a "Digital Twin for a 10 MW Electrical Drive System for Future Electric Aircraft Application" is presented. A digital twin platform is based on an outer-rotor permanent magnet synchronous machine and serval interleaved multi-level SiC-inverters, which allows the usage of high switching frequencies and a high DC link voltage of 1500 V. The combination of those components have advantages in future electric aircraft applications. Several multi-level inverter topologies have been investigated and a first system design for a 10.5 MW inverter system is presented.
