The Dielectrics, Conductors & Plasmas Competence Center responds to the challenge of introducing new functions into vehicles via the multiplication of electrical components that drive several engines at all levels of these new services sought by industry. The finality is completely autonomous vehicles. When combined with the goal of hybrid electric or all-electric propulsion, these challenges lead to a very significant increase in electrical power, and therefore in the voltage of electrical networks of on-board applications (aeronautics, space, rail, and automotive). While the terrestrial transmission of electricity already copes with much higher voltages, the mass and volume required for on-board applications radically change the problem: electrical constraints such as electric fields are significantly increased due to the low distance.
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 electrical arcs.
The center therefore researches, characterizes and models these physical phenomena (partial discharges, space charges, electrical arcs, and electrical ageing of insulators). In addition, it examines the application of suitable innovative dielectric materials (insulators, polymers, etc.).
In a quest to increase voltage, the center’s second area of enquiry is that of electrical currents. To minimize the mass of on-board electrical components, the center researches innovative electrical conductors.
