A new 2D/3D FEA based thermal model for magnetic components

Since the temperature rise is one of the key parameters in the design of magnetic components, thermal models are commonly applied in order to calculate the temperature value. Finite element analysis (FEA) tools are typically used to visualize thermal distributions but not for obtaining a model from the field calculation. This work presents a new thermal model based on the use of a thermal network whose parameters are obtained from 2D/3D FEA analyses. The model is suitable for any geometry and any thermal distribution. Comparisons of the proposed model with measurements and FEA simulations are also presented.
