Abstract :
A simplified hysteresis model, based on Jilesatherton modelling is proposed. Available in the case on constant flux level functioning, it allows to separate hysteresis and eddy currents contributions, the last one being possibly modelled as a simple frequency dependent resistance. An application to flux estimation is also proposed in the particular case of a single phase transformer.
