and al." EMI couplings from automotive traction systems

Abstract—Electric drive systems for vehicles are in-tegrated into today’s passenger cars by almost every car manufacturer. From the EMC point of view, the integration of electric drive systems into cars repre-sents a substantial challenge. The conventional EMC procedures and techniques are not appropriate for the new components. In this paper, an electric drive sys-tem is investigated which is source of electromagnetic interference within a passenger car. A model for sim-ulating coupling paths in the frequency domain, for standard cables as well as for shielded cables is devel-oped and confirmed by measurements. The obtained results have been used to determine the acceptable noise level emitted by the power converter on the high-voltage cables of a drive system
