Abstract
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.
