Liten is a major European research institute and a driving force behind the development of the sustainable energy technologies of the future. The institute is spearheading the EU’s efforts to limit dependency on fossil fuels and reduce greenhouse gas emissions in three key areas: renewable energy, energy efficiency/storage and development of materials.
Our platforms, sophisticated tools for industry & the scientific/technical infrastructure/expertise to overcome technological hurdles
Liten's research teams work across a vast portfolio of renewable energy technologies. Cutting-edge photovoltaic technologies are developed at INES, the French National centre for solar research and R&D with Hydrogen and Biomass activities being managed from the LITEN's main site in Grenoble, Rhone-Alpes.

A power transformer with
satisfactory thermal performance was produced using powder injection molding
(PIM) and a printed-circuit-type industrial assembly. This advance will pave
the way to smaller power supply components suitable for a variety of mobile
Liten, a CEA Tech institute, developed a soft magnetic material (ferrite with low magnetic losses) offering excellent performance at high frequencies. It has the potential to reduce the mass, volume, and cost of power converters. The material, produced in batches of several kilograms, was powder injection molded (PIM) to obtain the power converter's magnetic core.
The process, which Liten has the capacity to complete in-house, structures the material to a level of detail under a millimeter. It also gives the material a geometry that is compatible with thermal management and good integration into the final component. Furthermore, PIM does not alter the material's intrinsic properties and is suitable for the complex shapes inherent to 3D design and necessary for power converter integration.
The component was proven functional in research conducted in partnership with another CEA Tech institute, Leti, on a transformer prototype in a 60W power component (which covers virtually all PC, tablet, and phone chargers). Power densities of 6W/cm2 were obtained, compared to 1W/cm2 with conventional technologies.
The advance will be of interest to a wide range of markets, including power converters for electric vehicle battery charging systems, as well as mobile electronics and data centers.
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.
