摘要
The paper reports on the estimation of the distribution of currents flowing in a metalized part, starting from two-dimensional maps of the magnetic field induced above the part, with the monitoring of power semiconductor dies in view. The estimation is obtained from the measured data by inverting a mesh-free modeling of the induced magnetic field. First inversion results of experimental data are presented and discussed.
