Abstract :
This paper presents a method to obtain the magnetic field in the (x, y) tangential direction on a DC bus. Effectively, the local measurement of this signal will give us the current density repartition profile on the bus, in the 400 - 10 MHz frequency range. The magnetic field repartition has been identified and show us the geometry and skin effect influences on this distribution. A special sensor has been designed to allow us this measurement in the frequency range.
