The SiC RHBD power devices developed during this SBIR program is fundamental to a wide range of NASA PMAD and motor control applications. For DC-DC converters, the SiC power devices will connect power sources in a wide variety of NASA mission with various loads like electric propulsion, communications systems, instruments and actuators. The radiation-hardness, high-temperature capability, fast switching speeds, compact form factor and low mass offered by the proposed SiC MOSFET power converters will be invaluable for future NASA science missions. Switchmode power supplies improved by high frequency, high temperature power switches developed in this program are critical for NASA synthetic aperture RADAR's (SAR) antenna array T/R modules. T/R modules typically operate in a pulsed mode, drawing current pulses from a power supply on a periodic basis determined by the operation of the overall RADAR system. Air-Force propulsion system externals like actuators, pumps, and starters, weapons ejection, fuel transfer, lighting, avionics, RADAR, landing gears & breaks, steering, powered doors and ramps, gun drives, anti-icing, environmental control and auxiliary emergency power systems. The realization of a high power density switchmode power supplies and DC-DC conversion circuits will benefit Army's Future Combat System (FCS) by offering it an important part of the subsystem. An integrated electric power system made using SiC high power devices will increase component placement flexibility within vehicles, double fuel economy by continuously operating smaller engines under optimum conditions, and reduce armor protected volume. It will also enable an increased acceleration and maneuverability due to immediate torque to the wheels or tracks, reduce vehicle thermal and acoustic signatures and reduce system cost and logistics requirements. Commercial switchmode power supplies will also benefit from the development of such components.
