Recently realized radiation-hardened Gallium Oxide (Ga2O3) MetalOxideSemiconductor Field-Effect Transistor, (MOSFETs) offers the opportunity to increase efficiency and power density of space DC-DC power converters. The state of the art for space DC-DC power conversion trails its commercial counterparts in terms of power density and efficiency. One challenge that arises when designing for space environment is the harsh environment power converters need to operate in, and limited availability of space qualified components and field demonstrated converter topologies. Another challenge is the manufacturing process and reliability testing of reliable radiation hardened power MOSFETs. Ga2O3 MOSFETs not only have better electrical performance than power MOSFETs, they have also demonstrated inherent tolerance to radiation. This results in fewer structural device modifications required to make Ga2O3 MOSFETs operate reliably under high radiation compared to their Silicon counterparts. Syrnatec, an ITAR compliant, HUBZone, minority woman-owned small business seeks to utilize its radiation hardened Ga2O3 High Power MOSFETs to implement a Fixed Frequency Isolated Phase Shifted Full Bridge DC-DC Converter that supports 10 kW of power over a wide-temperature (-70ºC to 150ºC), provides high-power-density (>2 kW/kg), high-efficiency (>96%) power electronics with associated drivers for voltage regulation. Potential NASA Applications (Limit 1500 characters, approximately 150 words): Proposed 10KW WBG DC-DC converter will address Lunar and Mars base initiatives. This Power Converter will also benefit other NASA Mission Directorates - Science Mission Directorate and Aeronautics Research Mission Directorate. Specific projects that could find value include Gateway, In-Situ Resource Utilization, Advanced Modular Power Systems, In-Space Electric Propulsion, Planetary Exploration and Electrified Aircraft Propulsion Technology. This technology will be used for Mars, Asteroid research and search of life on other planets missions. Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words): Off-highway, Mining and Construction Vehicles, Power, for Telecom Infrastructure, E-Vehicle Charging Stations, Renewable Energy Conversion Electronics, Combat Ground Vehicle Systems, Aviation Systems, Electrical Power Systems for Telecommunication Equipment Duration: 6
