Influence of Material Dynamic Hysteresis Modelling in Losses Computation
Résumé
In electromagnetic applications, hysteresis phenomena in magnetic materials are responsible of considerable causes of losses especially in transformer modelling cases. In specific case, such as current sensor, the output signal can be modified because of this loss. The paper presents the implementation proceeding used for some hysteresis material models and how they are applied in a sensor study case. A priori loss computation, simultaneously carried out with the simulation is one of the main advantages of this implementation. A transformer application is performed with the dynamic hysteresis characteristic taken into account and compared with experimental measurements.
