| Abstract |
Accurate modeling of the losses generated in magnetic components is becoming critical as power and operating frequencies ramp up. Core loss models in literature focus on the calculation of losses per volume unit, but the non-uniform distribution due to the material properties and geometry is barely addressed. In this paper a model for the losses of the ferrite core in planar magnetic components is presented, which provides a fast and accurate estimation of the non-uniform flux distribution. The magnetic model is coupled to a thermal model to obtain the temperature distribution. The coupled model is verified using Finite Element simulations, demonstratingan error of 3 \% with execution time of seconds. |
