Design, optimization and electromagnetic modeling of integrated passive components for power electronic

New structures of integrated passive components, based on both planar and cylindrical sub-components are introduced. This paper investigates the trade-offs between dimensions, thermal behavior and electromagnetic performances of the structures. The electromagnetic limits are analysed in terms of physical dimensions and thermal dissipation capabilities. An example of a forward SMPS output filter is used to illustrate the analysis. A high frequency electrical model of the sub-components is then proposed. This model is based on the transmission line theory.
