So I am modelling
the magnetic core in Pspice model editor
I got the B-H curve values from the TDK mcironas ferrite design
magnetic tool and uploaded that into pspice model editor
I also referred to the
for modelling the magnetic core
The values mentioned in the book matches with the ?
But the issue is the Pspice model editor uses Jiles Atherton model
to calculate the parameters Ms , A , C and K
When I give the B-H curve values into the Pspice model editor ,
the model editor internally somehow calculates the above mentioned
parameters which is way too far away from the ones mentioned in
the book (there is no values of MS , A , C and K mentioned in the
datasheet)
And when I give the parameters from the book into the Pspice model
editor , the curve does not fit and I am not getting the expected
results
Any idea on how to resolve this ?
Below table shows both the book values (2nd column) and spice
model editor values (3rd column)
