Power Electronics Platform

Achieving optimal performance and accelerating the adoption of GaN and SiC technologies

Published on 4 November 2022


Achieving optimal performance and accelerating the adoption of GaN and SiC technologies

The platform is developing innovative substrates, components, and architectures devoted to power conversion, from the design stage to a functional demonstrator. With pre-industrial equipment, it offers customized support to industrial partners.

The platform is open to the transport industry (two-wheelers, automobiles, rail transport), data centers, photovoltaics, etc. R&D projects have three objectives: 

  • improving conversion and energy efficiencies in systems; 
  • making innovative components and systems more reliable, or even qualifying them for targeted applications, aiming for performance that is at least equivalent to that of marketplace silicon solutions; 
  • reducing manufacturing costs to facilitate access to new high-power materials such as SiC. 

100 platform researchers provide a triple expertise in substrates, components, and innovative conversion architectures. They rely on a 200 mm and 300 mm microelectronic production line to validate manufacturing processes and accelerate industrial transfers.

​What expertise is provided to industrial stakeholders?

• Substrate engineering
• Epitaxy processes
• Innovative power transistor architectures
• Power circuits and energy conversion systems
• Power modules

Cutting edge preindustrial equipment

• MOCVD epitaxial reactors
• High voltage testers
• 200 mm and 300 mm silicon and III-V microelectronic production line

How to work with the power platform

CEA-Leti’s teams support the needs of its industrial partners (major groups, small and medium-sized companies, and startups) across all or some stages of development, using bilateral contractors or shared laboratories. The platform hosts about twenty industrial partners from the microelectronics sector or specialized in power components. Amongst them are Renault, Schneider Electric, Soitec, STMicroelectronics, Valeo, etc. Partnerships have been established with several of these industrial market leaders.
