KEY COMPETENCE
high voltage energy
We aim to respond to the challenges of reduction of the environmental footprint of transport through electrification solutions. Indeed, we focus on the increasing need for electrical systems, for which either non-propulsive or propulsive energy is leading to a significant rise in electrical power need, and therefore in the voltage level.
In addition, densification is essential to allow a drastic reduction in the weight and volume of electrical equipment and systems. Indeed, these performance indicators raise non-negligible constraints when it comes to embedded applications: some, such as electric fields, increase considerably due to the small distance between them.
Objectives
These electrical constraints, combined with the harsh environments of aeronautics and space (temperature, pressure, etc.), aggravate phenomena detrimental to the integrity of electrical systems, such as partial discharges or electric arcs.
Therefore, we research, characterize, and model these physical phenomena (partial discharges, surface discharges, space charges, electric arcs, and electrical aging of insulators). In addition, we examine the application of suitable innovative dielectric materials (polymers, polymer matrix composites, etc.).
In a quest to increase power, we are also focusing our efforts on the study of electrical currents. To minimize the weight of onboard electrical components, our teams focus their research on innovative electrical conductors.
