Converters
Overview
- Power converters are an essential component in most EAP aircraft concepts, as they are used to convert from ac to dc power, or vice versa
- NASA is sponsoring or performing work to achieve power densities 2-3 times the state of the art for converters in the MW or larger class.
- Silicon carbide and gallium nitride converts are being developed with conventional cooling as well as a cryogenically cooled converter
