Zusammenfassung, Abstract
Due to the increased exposure to cosmic radiation at higher flight altitude a significant voltage derating of power semiconductors is required to reduce the failure rate of the inverters designed for electrified aircraft propulsion systems. By utilizing the necessary oversized block-voltage capability of the power semiconductors while employing the concept of variable DC-link voltage post-fault performance of the inverter system can be improved.
