Contribution à la conception, par validation numérique et expérimentale, et l’optimisation pour l’aéronautique de contacteur hybride haute tension DC

Abstract : The main goal of the more electrical aircraft is to substitute the different kind of transmission for the aeronautical power by electrical transmissions. The electric network has to evolve. This concept inspires the project AEROCOTS, which a part lies in the modification of the breaking means thanks to a hybrid contactor with an electrical circuit. To better understand what occurs between the contacts of the contactor and verified the absence of an electrical arc, a characterization method is employed to have a complete parameterized model of a contactor. Two electrical circuits are studied and the absence of an arc is verified. Their principle is to reduce to zero the current before the opening of the contactor. Their functioning and their models are experimentally verified. The choice of the second circuit is justified by a control of the opening current. An evolutionary algorithm, principle of the Darwin's theory, is realized to answer to the aeronautical objectives
