GE Aerospace has successfully completed qualification testing for two advanced high-voltage power electronics systems designed to support the U.S.Army’s transition toward more electrically powered combat vehicles.

The systems, known as the High-Voltage Power Controller (HVPC) and the Unidirectional Converter (UDC), are now considered ready for production after meeting Army requirements.Low-rate initial production is expected to begin in 2026, with deliveries scheduled for 2027.These technologies enable military vehicles to move from the traditional 28-volt electrical architecture to a much more capable 600-volt system.

The higher-voltage approach allows vehicles to generate, distribute, and manage significantly more electrical power while reducing energy losses, decreasing wiring weight, and improving overall efficiency.

The Army's growing demand for onboard electrical power is driven by increasingly sophisticated equipment, including advanced sensors, communications systems, electronic warfare capabilities, artificial intelligence processors, active protection systems, and potential future directed-energy weapons.

A key component of the new systems is silicon carbide semiconductor technology, which can operate at higher voltages and temperatures than conventional silicon while producing less heat.This improves efficiency, reduces cooling requirements, and allows for smaller and lighter power systems.GE Aerospace has collaborated with the Army on silicon-carbide-based power technologies for nearly a decade.

The newly qualified systems also incorporate the company's proprietary Power Overlay Packaging technology to improve thermal management and power density.

Although no specific vehicle programs were officially identified, the technology could support current and future platforms such as the Bradley Fighting Vehicle, Armored Multi-Purpose Vehicle, Paladin self-propelled howitzer, XM30 infantry vehicle, and the future M1E3 Abrams tank as part of broader Army modernization efforts focused on hybrid-electric propulsion and enhanced onboard power generation.
