| Abstract |
This paper presents a practical method for predicting the core losses in magnetic components for an arbitrary shape of the magnetizing current.
After comparison of several existing core loss models the calculation of the specific core losses by means of the Steinmetz equation as usually done by the suppliers of magnetic materials will be presented. However, the exponents used in this equation are normally
derived from measurements with sinewave currents. In this paper the mathematical background is presented of how to use these data also for the real current shapes occurring in
switch mode power supplies. This theory is verified by measurements. The paper ends with a short discussion of the obtained results. |
