By using GE-developed SiC technology, we have the potential to reduce the weight on the aircraft by more than 400 lbs. while also delivering higher performance and freeing up precious cargo space. The new line of products includes AC-DC, DC-DC and DC-AC converters and special purpose power supplies such as battery chargers and frequency converters.

—Vic Bonneau, president of Electrical Power for GE Aviation, Systems

Bonneau noted that on board airplanes, space and weight are premiums. Airlines are constantly trying to balance the need to create more passenger and storage space, while also meeting increased demand for electrical power on the plane.

SiC power devices are superior to conventional silicon devices because they can operate at much higher switching frequencies, junction temperatures and voltages. The higher frequency operation allows many of the supporting electrical components to be significantly reduced in size and weight which is critical for airborne applications. The devices are also able to operate in the high temperature environments of ground vehicles and the high voltage capability will enable future higher-power vehicle power systems.

The introduction of the new line of SiC-based power conversion products is the result of R&D that started in GE research labs. The SiC power conversion is part of a broader, long-term research strategy GE is pursuing in advanced energy conversion technologies to address the ever-increasing demand for electric power in Aviation and other industries such as energy and healthcare.
