Research description:

Our activities encompass two different axes corresponding to the two components of electrical engineering: power engineering and power electronics. The common factor is the dielectric material. Hence as regards fundamental studies, research works may be undertaken concerning the characterization, the modeling and the study of new materials devoted to specific applications in any of the previous domains. Applied studies may also be developed mainly concerning the reliability of electrical devices and apparatuses in which these materials are often considered as the weakest points. Whatever the case, these works need a multidisciplinary approach (from material science to electrical engineering).
