The French Cluster MEDEE and several of its members (L2EP, LSEE, URIA and LAMIH) are involved in an ambitious R&D French project called CE2I “Integrated & Smart Power Converters” (budget: €10M). This multidisciplinary project will create the electric motor of the 21st century. CE2I develops a system integrating a reliable electromagnetic actuator and a static converter based on large gap components. This package will be fault-tolerant, remote programmable and will have to meet the requirements of compactness, eco-efficiency and modularity (plug and play) to satisfy a large range of applications such as on board systems, renewable energy production, electrical mobility and industrial process reliability. CE2I has already received a lot of support from industrial stakeholders. The presentation will give you an overview of CE2I.
