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

Abstract

For electromagnetic interaction analysis in power electronics, the study and the design of Near-Field integrated magnetic antennas are presented. An antenna model is developed and compared to experimental data. The modeling and the performances of the prototype is discussed in function of the source position and the antenna design.

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

“…This principle is illustrated Fig.2. It includes the sources, the magnetic couplings and the magnetic antenna constituted by the conductive loop, the access lines and the measuring instrument represented by the termination load RM [8]. Thus, in addition to the magnetic field measurement, the antenna loop can be used to estimate currents flowing in the circuit.…”
