Influence of the Size and Shape of Magnetic Core on Thermal Parameters of the Inductor

In this paper, a new thermal model of the inductor is proposed. This model takes into account self-heating in the core and in the winding, and mutual thermal couplings between the mentioned components of the inductor. The form of the elaborated thermal model is presented. In this model, the influenc...

description In this paper, a new thermal model of the inductor is proposed. This model takes into account self-heating in the core and in the winding, and mutual thermal couplings between the mentioned components of the inductor. The form of the elaborated thermal model is presented. In this model, the influence of power dissipated in the core and in the winding of the inductor on the efficiency of heat removal is taken into account. Correctness of the model is verified experimentally for inductors containing ferrite cores of different shapes and dimensions. The good agreement between the results of calculations and measurements is obtained. On the basis of the obtained findings, the influence of volume and the shape of the core on thermal resistances and thermal capacitances occurring in this model is discussed.
