Abstract :
As planar technology is finding its way into applications replacing the conventional wire wound magnetic components, new design tools for these components are needed. As thermal problems can be a limiting factor for an electronic system, a thermal model should be part of the design process. We have developed a thermal model for planar transformers and applied it to an E-PLT22/16 transformer with a 4-layer PCB. The model follows the 3D geometry of the component and provides links to the environment. It is fast, parametrisable and applicable for a broad range of user-specified boundary conditions. The model is compared with measurements.
