Modeling of the near-field electromagnetic radiation of power cables in automotives or aeronautics

This paper presents an analytical method to compute at low simulation cost the electromagnetic near-field emitted by common mode currents in power cables supplied by power converters in automotive or aeronautics. Various cable configurations are considered: single, double or triple strand. A specific experimental bench has been built in order to verify the validity of our predictions. We show that the method enables to characterize the level of radiation of a cable versus a specific standard and that it is possible to optimize its shielding in order to minimize its weight while keeping a satisfactory efficiency.
