GE Aerospace qualifies SiC solutions for military vehicles
GE Aerospace has qualifeid its High-Voltage Power Controller (HVPC) and Unidirectional Converter (UDC), marking both products as production-ready for US military ground vehicles.
The High-Voltage Power Controller and Unidirectional Converter both use GE Aerospace’s SiC MOSFET, Power Overlay Packaging (POL) and module technologies, delivering what are claimed to be best-in-class size, weight, power, and cost advantages.
“The power, temperature and thermal capabilities of these units are unmatched in the industry,” said Kris Shepherd, president and general manager, electrical power systems for GE Aerospace. “With this qualification complete, these high-voltage power units are ready for production and represent a significant technology advancement in power electronics to deliver the power required for military ground vehicles.”
Low-rate initial production of the HVPC and UDC is anticipated in 2026, with deliveries to the US Army expected to begin in 2027.
The technology was developed in collaboration with the US Army Combat Capabilities Development Command Ground Vehicle Systems Center (DEVCOM GVSC) and qualified at GE Aerospace facilities. These high-voltage units shift from a traditional 28V system to a 600V architecture, enabling more efficient energy conversion and battery charging while reducing weight and easing demand on the motor. This allows the motor to dedicate full power to driving the vehicle when needed.
“This 600V qualification marks a critical milestone in the advancement of high-power vehicle architecture with potential application throughout the US Army’s current combat vehicles enabling the next generation of warfighting capability,” said Jason Spina, Power System Architect, Ground Vehicle Power & Mobility, Combat Capabilities Development Command (DEVCOM) with the US Army.
