Description
The implementation of cryogenic distribution systems with solid-state switches, such as those required in hydrogen-electric aircraft, faces challenges in achieving both electrical and thermal isolation for gate drivers. Traditional methods, including magnetic and capacitive isolation, are unsuitable for systems requiring thermal isolation. Power Over Fiber (POF) addresses both the thermal and electrical isolation challenges by leveraging the low thermal conductivity of glass and its demonstrated efficiency in transmitting power under cryogenic conditions. Both of these advantages make it a prime candidate for providing isolated power to solid-state switch gate drivers. This article will characterize the performance of an 850 nm POF converter across temperatures down to 100 K.
