The « Agence de l’innovation de défense » (AID – for Defense Innovation Agency), created on September 1st, 2018, is an organization of the French Ministry of Armed Forces. It brings together the ministry’s innovation initiatives by ensuring the coordination and consistency of all the approaches implemented.
The AID notably supports research on military and dual themes (civil and military). The AID defines its own scientific themes priorities and funds doctoral studies in these themes.
This Tuesday, December 3rd, 3 winners received the 2024 thesis prize for the excellence and originality of their work.
Among them, Laurine CUROS, former doctoral student at the IMS Laboratory, was rewarded for her thesis entitled: « Destruction effects modelling of electronic equipment power supplies due to high level conducted electrical pulses. »
This thesis was carried out and supervised in collaboration with CEA DAM Gramat (F. Puybaret) and the IMS Laboratory’s Reliability research group (T. Dubois, J.M. Vinassa).
Summary of her doctoral thesis:
Intentional Electromagnetic (EM) interferences such as High Altitude Nuclear EM Pulse (NEMP/HEMP) are able to generate electrical disturbances, similar to those produced by lightning. NEMP couples efficiently on aerial lines of the electricity distribution network and propagates into the power supplies of electronic equipment. Several studies exist and have shown the destructive effects of these high current level pulses on electronic equipment. Few of these studies focus on understanding the origin of these destructions. However, an advanced understanding of the power supplies failure mechanisms is the key to predict destruction. In this approach, experimental and theoretical research is implemented to predict numerically the electromagnetic interference effects on electronic power supplies. This work allowed to develop a complete failure scenario for an electronic power supply as well as to determine the main modes leading to the failure of each sensitive components. By associating the failure models of components, we are then able to simulate numerically the proposed scenario and therefore predict the destruction effects induced by high level current pulse injection on power supplies.
