This paper presents an electrothermal model of ferromagnetic cores dedicated for SPICE software. The form of this model, dedicated to be used in power electronics applications, is presented and the procedure of estimating magnetic, geometric and thermal parameters of the presented model is proposed. The correctness of the proposed model is verified by comparing the calculated and measured characteristics of the selected ferromagnetic cores operating at different values of flux density, frequency, ambient temperature and cooling conditions. The satisfied agreement between the results of calculations and measurements is obtained.

W pracy zaproponowano elektrotermiczny model rdzeni ferromagnetycznych dla programu SPICE, dedykowany do analizy układów energoelektronicznych. Przedstawiono postać modelu oraz sposób wyznaczania jego parametrów magnetycznych, geometrycznych oraz cieplnych. Poprawność prezentowanego modelu została zweryfikowana przez porównanie obliczonych i zmierzonych charakterystyk wybranych rdzeni wykonanych z różnych materiałów i pracujących przy różnych wartościach indukcji pola magnetycznego, częstotliwości i temperatury otoczenia oraz przy różnych warunkach chłodzenia. We wszystkich przypadkach uzyskano dobrą zgodność między wynikami obliczeń i pomiarów.
