An Advanced SiC Power Switch for Deep Space Power Systems
We propose to design and fabricate advanced SiC power switch aimed at up to several kilowatt power system applications. The power switch is expected to lead to (i) substantially reduced volume and weight of space power systems, (ii) greatly expanded operating temperature range, and (iii) drastically improved power efficiency and enhanced radiation tolerance. In Phase I, we propose to design, optimize, and compare different SiC power switch structures. DC and high-speed transient characteristics will be systematically studied over a wide temperature range. Concentration will be focused on achieving operations with highest possible power density, efficiency, and speed over a wide temperature range. We also propose to perform experimental work to develop all of the critical process technologies in Phase I. In Phase II, we shall apply the developed technology to fabricate the advanced 4H-SiC power switches up to 5 kW and use them to demonstrate the operation of a motor control system showing the true advantages of an all-SiC power converter.
