Electromagnetic antenna for power electronic modules: Towards a real time electromagnetic characterization

This study deals with near-field probes integration onto power electronic modules for the magnetic field measurement. In this paper, electromagnetic disturbances characterization is investigated. A loop-antenna-type, its design and its modeling are detailed. The measurement obtained on a buck power converter are presented. An analysis of conducted currents within the power module is developed. Based on them, it is shown that the probe measurements allow recovering the characteristics and the distribution of the electromagnetic disturbances.
