An Efficient Method for Modeling the Magnetic Field Emissions of Power Electronic Equipment From Magnetic Near Field Measurements

Résumé

In this article, we present an efficient modeling of sources of electromagnetic disturbance using the measurement, in near-field, of the magnetic field radiated from a power electronic equipment. A model based on elemental magnetic dipoles is developed for the prediction of the radiated magnetic field. This model is obtained from measurements in the near field. For the determination of the parameters of the model, an optimization procedure is combined with a matrix inversion. Unlike standard approaches, this new technique allows to find equivalent sources with a small number of dipoles in a reduced computing time. To check the efficiency of the proposed method, we perform a comparison between a classical optimization method and the new procedure. To validate this method experimentally, near field magnetic measurements are performed to find the equivalent model in case of a mono turn coil, a toroidal coil and a DC/DC converter.
