Technical Abstract (Limit 2000 characters, approximately 200 words):

Cornerstone Research Group, Inc. (CRG) proposes to leverage recent technology advancements with digital high voltage fault protection of industrial AC and DC grid serviced infrastructure to enable safe, reliable electric propulsion power systems for urban air mobility. CRG is currently working with a Silicon-Carbide (SiC) switching technology partner for a DoD Phase II effort focused on building a full-scale hardware system to demonstrate the ability to protect aircraft secondary electrical grid for the V-22. SiC provides ultra-high speed micro-second switching with 1,500 VDC and 1,000 VAC switching capability along with series electromechanical switch providing galvanic isolation. Electronic and electromechanical switching combine to warrant established reliability fault protection for emerging aerospace high voltage electric power systems. CRG’s track record of innovation in power and energy technology development including hybrid power systems, high efficiency power converters, and battery packs coupled with our partner’s expertise in SiC solid state relays and fully digital circuit breaker technology will deliver successful development of a high voltage digital circuit breaker protection system meeting NASA’s mission goals for safe and reliable advanced air vehicles.
