Common Mode Noise Propagation and Effects in a Four-Wheel Drive Electric Vehicle

摘要

New topologies of electric car use high power switching devices which must be integrated with a growing range of electronic systems in small places. A good performance of the car relies on the electromagnetic compatibility among these systems, which requires the characterization of the noise and interferences present in the system. To characterize the noise, both emission and susceptibility issues as well as coupling mechanisms must be studied. This paper presents the work performed for the electromagnetic mapping of a four-wheel fully electric car, which involves both simulation and experimental measurements. It has been carried out within the E-VECTOORC project (FP7-INFSO-284708), in collaboration with car manufacturers such as Jaguar Land Rover and Škoda.
