Abstract
Medium voltage DC (MVDC) is an emerging technology to enable the transmission and distribution systems of electric aircraft to be more lightweight and efficient. In this paper, a performance comparison is presented between three options of megawatt-scale medium-voltage (MV) power inverters based on Silicon Carbide (SiC) power modules. These three options include: two-level MV inverter based on 3. 3kV high-voltage SiC modules, two-level MV inverter based on series connections of 1. 7kVSiC modules, and three-level active neutral point clamped (ANPC) MV inverter based on 1. 7kVSiC modules. Specifically, the efficiency and reliability have been compared and discussed, which will provide a reference for engineers and researchers to develop electric aircraft propulsion drives in the future.
