Fault interaction between inverter and electrical machine, at electrical and electromagnetic level, used in HEV's application

摘要

The electrical propulsion system in Hybrid Electrical Vehicle (HEV) contains: the electric machine, the controller and the inverter. Several paper model and interpret each component separately without considering the interaction between those elements. In this paper, the electrical aspect of the inverter will be investigated as a preface to build a global model combining the inverter and the electrical machine. Hence the electrical model of the inverter will be built. Then, electrical faults in the inverter will be integrated and the impact of this faults on the electrical and electromagnetic performance of the electrical machine will be displayed.
