Choix d'un matériau optimal pour un capteur de courant
Résumé
A computer aided design (CAD) tool dedicated to a closed loop sensor current is described here. Lastly, a step by step temporal model, including flux leakages, magnetic material saturation and the dynamical behaviour of the magnetic material that can be described with a circuit type software (PSPICE) is supplied. This model has been tested and compared to measures realized on the existing device. This model, can also virtually test some new technological solutions as a change of the magnetic material. Three magnetic materials have been tested with this tool and an analysis of the results is provided.
