We propose to develop power semiconductor devices (diodes and transistors) for power-management and actuator-control circuits operating at cryogenic temperatures. Cryogenic power electronics can provide important benefits both for space and commercial applications: higher efficiency, reduced size,… More

We propose to continue development of power semiconductor devices (diodes and transistors) for power-management and actuator-control circuits operating at cryogenic temperatures. Cryogenic power electronics can provide important benefits both for space and commercial applications: higher efficiency,… More

It is predicted that systems for power generation, power distribution and electric propulsion on ships and aerospace vehicles could be made smaller, lighter, more efficient, more versatile, and lower maintenance by operating these systems-partly or entirely-at cryogenic temperatures. We propose to… More

Our goal is to demonstrate the advantages of… More

Ultrasensitive sensors used in NASAs scientific missions (for example infrared sensors) typically require operation at deep cryogenic temperatures for optimum performance. However, to make full use of their performance requires an ultralow-noise preamplifier co-located in the same, or a nearby,… More

The proposed innovation is a motor-control subsystem capable of operation in extreme environments, including those to be encountered on the Moon and Mars. Specifically, we will demonstrate operation over the environmental range from +130ýýC down to ýý230ýýC during Phase 1, and from +200ýýC… More
