EM-Matrix antenna for real-time measurements of electromagnetic noise in power electronic modules

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

“…If the loop radius is sufficiently small, the magnetic field can be considered homogeneous inside it. The electromotive force is so expressed by (3). A relation is established between the output voltage of the antenna and the normal component of the magnetic field at the antenna center .…”

“…To reduce time costs of the magnetic field investigations, the integration of several loop antennas onto electronic modules has been studied previously [3], [4]. That represents a first approach of the "insitu" magnetic field measurement.…”

Theoritical and experimental study of magnetic sensors for near-field emission measurement: Application to design and integration in power printed board circuit

“…However, the main drawback of NF scanning technique is the time consumption to collect all the samples, especially in Power Printed Circuit Board (PPCB) and Hybrid 3D structures. Due to their large size and to the 3D top surface, the scanning step and time characterization of such measurement systems does not allow an "in situ" and real time measurements To overcome this drawback, the solution developed in this study is based on sensor integration onto the given electronic module, as started in [5] [6]. First prototypes of magnetic probes are studied in this paper.…”
