AN INVERSIBLE MODEL FOR HYSTERESIS CHARACTERIZATION AT CONSTANT FLUX AMPLITUDE

Damien Halbert - Erik Etien - Gérard Champenois

   A new model, available in the case of constant flux amplitude is presented. It allows to consider global closed loop modeling of the phenomenon. The model obtained is linear with its parameters, and their estimation is then simplified and done using linear least square algorithm. An application to a single phase transformer is proposed in order to validate the proposed method.
