Common Mode Modeling of the Association of N Switching Cells - Application to an Electric Vehicle Drive System

The reliability of electronic systems is a major constraint depending on electromagnetic interference levels. Vehicle manufacturers are clearly concerned by electromagnetic compatibility (EMC) studies and especially for electrical drive systems in which embedded power electronic is used and must thus be correctly designed. A global synthesis of common mode disturbances of such equipment is pointed out in this article and a generic model of a complex power electronic device is presented and applied to a motor drive system.
