This paper deals with a magnetic modeling for the estimation of the dynamic
losses in soft ferrite cores. A time-domain MSPM based algorithm for the h
ysteresis losses evaluation, added to a simplified, one-dimensional modelin
g of the eddy current losses, are used to predict the total specific losses
in cores subjected to a.c. and distorted wave-forms. Experimental analysis
show satisfactory capability of prediction of the modeling proposed, used
as a CAD tool.
