Abstract

Electric aircraft using hydrogen-powered fuel cell is a promising solution to meet the aviation industry's net-zero carbon emissions target. Airbus UpNext launched the ASCEND project in 2021, which aims to investigate the potential of applying both cryogenic and superconducting technologies on a powertrain demonstrator. Cryogenic DC-DC converters are critically needed for fuel cell and batteries to maintain stable DC bus for electric propulsion system. A 10-kW bidirectional DC-DC converter prototype based on SoLid Cover IGBTs is designed and built. The performance of the cryogenic DC-DC converter prototype in buck mode and boost mode is investigated and experimentally tested. Power losses and efficiency are also analysed. The cryogenic bidirectional DC-DC converter prototype demonstrates successful operation with improved performance in cryogenic temperature environment.
