Abstract:
This paper presents the design and development of a 120-V, 10-kW flexible dc energy router (FeDER), explicitly tailored for use in dc microgrids on the lunar surface. The FeDER, structured as a T-type solid-state circuit breaker (T-Breaker), utilizes gallium nitride (GaN) devices to achieve both high power density and efficiency. Its design philosophy and component selection have been tailored to operate in cryogenic temperatures as low as 77 K. Its thermal dissipation system is designed to handle operations under vacuum conditions. The completed FeDER prototype features a power density of 89 W/cm3 and an efficiency of 99.75%.
