Summary
The Space Power Conversion Electronics (SPCE) program seeks to address the power limitations of small satellites in low Earth orbit (LEO).
SPCE focuses on developing high-voltage, radiation-tolerant transistors and integrated circuit technologies to improve the efficiency of point-of-load (POL) power converters in the harsh space environment.
Conventional space POL systems suffer from low efficiency (less than 60%), impacting satellite power availability, mission capabilities, and battery life. SPCE aims to overcome this limitation by exploiting advances in wide bandgap semiconductor (WBGS) materials, novel device designs, and heterogeneous material synthesis to create radiation-tolerant power transistors that rival the performance of terrestrial WBGS power transistors.
The program aims to demonstrate a highly integrated, radiation-tolerant POL converter with over 85% efficiency and a power density exceeding 500 W/in3. This technology will be crucial in meeting the demands of advanced mission capabilities and ensuring the longevity of satellites in LEO.
