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 studies and, especially, for electrical drive systems in which embedded power electronics is used and must, thus, be correctly designed. A global synthesis of common-mode disturbances of such equipment is pointed out in this paper and a generic model of a complex power-electronic device is presented and applied to a motor-drive system.
