Conception optimale d'un entraînement électrique pour la chaîne de traction d'un véhicule hybride électrique : Co-conception des machines électriques, des convertisseurs de puissance et du réducteur planétaire

Abstract : A new powertrain for a hybrid electric vehicle of heavy duty was developed in this research work. In this case, the design and the optimization of electrical components of powertrain have been investigated involving the permanent magnet synchronous machines, the associated inverters and the Ravigneaux train. Regarding the design, an analytical model was created and that permits simultaneously answering to specification. The various multiphysic constraints have been taken into account in analytical model. And then the numerical model was carried out via finite element method has been implemented. The numerical model allowed us to valid electrical machine performances. Regarding the optimization, a global optimization strategy was investigated. An optimization example was based on a system which was composed of two electrical machines, two associated inverters and the Ravigneaux train; The comparison based on this example between the local optimization and the global optimization, which allowed us to valid the advantage of global optimization strategy. The experimentation has been performed with a test bench involving the prototype machine and the load machine, the two electrical machines were fed and controlled by two frequency drives. The experimental results permit to valid the theoretical models.
