Methodology development for analytical modeling of hybrid vehicle’s electrical components: Energy performance optimization

The hybrid electric vehicle (HEV) is a complex system consisting of several energy sources. Depending on their configuration typically combining an internal combustion engine, electrical machinery and a storage system, significant benefits in terms of energy consumption as well as other  features can be achieved as compared to a conventional vehicle. In order to achieve this goal, optimization is required at different levels. For a given use, the energy performance of the HEV  mainly depends on three highly interdependent aspects:
-    The topology : series, parallel ...

High frequency modeling of synchronous magnet machines, Application to the early detection of inter-turn fault and demagnetization fault

Powertrain electrification in the transportation field is currently a strong trend. Permanent magnet synchronous machines (PMSM) are commonly used in this type of application because of their compact design and their high energy efficiency. In this context, the proposed PhD thesis concerns the detection of defects in PMSM right from their first appearance phase in order to plan maintenance time, to reduce repair cost and to increase machine availability.
