A high-density power converter/charger designed specifically for aeronautics
As part of the European NENUFAR project,
CEA has developed an innovative converter dedicated
to aeronautical applications. It charges the aircraft's
lithium-ion batteries and provides DC/DC conversion
to power auxiliary components such as instrument panels,
interior lighting and USB sockets.
Based on wide-band gap Gallium Nitride (GaN)
transistors, this converter features four 2 kW modules
that can be used separately or together. Its power
density is twice that of existing solutions.
This converter supports the aeronautics sector's move towards higher-performance electrical technologies: lithium-ion batteries to replace lead-acid batteries, high power density, reduced conversion losses, etc. It has two main functions:
• Low-Voltage lithium-ion aeronautical battery charger
•DC/DC converter (270V to 28V) for low-voltage buses.0It features analog controls that are impervious
to software errors.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
