Innovative Power Electronic Switch for Naval Applications in Extreme Temperatures

In this program, MTECH will develop a half-bridge building block optimized for extreme-temperature operation for various naval applications, especially those involving superconductivity or requiring high power density. After a Phase I feasibility and optimization study, a number of Phase II prototypes will be designed, fabricated and tested. The devices will target the Navy's objectives: power levels of 200-300kW, at least 6MW/m^3 power density, >200kHz frequency, >98% efficiency, and an operating temperature range of -225?C to 150?C, with an emphasis on cryogenic operation for superconducting applications. In this work, MTECH will adapt its extreme-temperature electronic devices for gas or conduction cooling, as is required by the Navy, and will characterize newly emerging devices.
