This paper deals with the broad-band modeling of a realistic power converter shield used in an electric vehicle. To validate such a model, comparisons between computation and measurements are required. As it is not practical to characterize experimentally the true radiation of a power converter through its enclosure, a reciprocal approach has been defined in which the enclosure is illuminated by a plane wave (receiving configuration). The associated experimental setup has been carefully defined and tested. At low frequency, the model is based on radiation through apertures in a simple cavity. At higher frequency, the Aseris-BE code, which is based on the boundary integral equations technique, has been used for computation. An optimal and realistic mesh of the enclosure suitable for the Aseris-BE code has been built by making numerous comparisons between computation and measurements, which have shown how to improve the mesh.
