Analytical model for magnetic components including self-heating effects

Analytical magnetic models are used when the winding strategy and the geometry of the magnetic component produces an 1D magnetic field distribution. Additionally, analytical thermal models can be used when thermal distribution, the geometries of the windings and the core produce an 1D heat flux distribution. This work shows how both thermal and magnetic analytical models can be coupled to obtain an accurate global model that allows magnetic designer the optimization of the magnetic component for a specific application based not only in magnetic information like maximum flux density, magnetic losses, etc, but also in thermal concepts like maximum temperature rise, heat flux, etc. The proposed approach is validated using finite element analysis and measurements.
