Radiated emissions modelling of a power cable

This paper presents two numerical methods to compute quickly radiated emissions of a cable linking a power converter and a motor. 3D model is not built to be compliant with industrial process (short time development). The field is directly deduced (thanks to Matlab programs) from the common mode current and the load impedance. Simulations are compared to measurements on an inverter mock-up designed by Airbus France. Measurement set-up is performed according to DO160 standards. Modeling results show a good correlation with measurements.
