Dear sirs,
I have some doubts regarding the iron losses model. We are simulating a simple ring core transformer with a material loaded from the library and defined by its k1,k2,k3, alpha1, alpha2, alpha3 parameters.
The results from the simulations are quite acceptable.
In order to draw a graphic with the power losses versus the maximum induction, I have used the Bertotti modified model equation using the same parameters used by the program. Surprisingly for me, the values obtained with equation are very far from those obtained as a result of the simulation.
How can this be possible? What could be the reason for it? Thanks for your help
