Accelerate the development of new magnetic components to meet the challenges of deploying large-gap semiconductors for power conversion. Incremental gains in magnetic component geometries are obtained in the state of the art by planar-type configurations, but a real breakthrough in terms of compactness and efficiency could be achieved by magnetic cores designed with gradients in magnetic properties. The aim of the project is to use indirect additive manufacturing (AM) techniques already studied at DMAT and DTNM to design innovative magnetic architectures by mastering the co-sintering stages. The project will culminate in an evaluation of a demonstrator (inductor) designed to attenuate critical parasitic phenomena occurring at the interfaces between conductors and the magnetic core. The magnetic materials will be ferrites already identified for high-frequency operation. The database on these materials, combined with the modeling tools developed and the feedback gained on FA processes, will enable a broader approach to power electronics applications.
