Optimisation d'une chaîne de traction pour véhicule électrique

TL;DRAbstract

The elements that can be found in traction chain are usually separate and independent between them (battery pack, traction converter and motor). The use of cascaded inverter in order to drive the vehicle has been the heart of this thesis. The energy performance of cascaded inverter and classical voltage source inverter were compared on a standardized driving cycle for different power converters configurations (voltage level for the traction chain, variation of the number serial inverter for cascaded H-bridge and different number of semiconductors in parallel to do the function of the power switches in converters). Other power electronic converters are necessary for the electrical vehicle. One of these converters is the battery charger which tranfer energy from the network to the vehicle's batteries. Another is the battery monitoring system that ensures a balance and uniform state between the different cells which make up the battery pack of the vehicle. With an objective of increasing
