Proposal for scalable models in EMC simulation

[摘要] In this paper a method "Component Series Modeling" (CoSeMod) is presented.This allows fast and easy implementation of scalable model generations forpassive component series based on measurement data or specification providedby manufacturer. These can be used in circuit models for fast EMC analysisand optimization, especially in frequency ranges where conducted emission andsusceptibility dominate. EMC tasks require high precision equivalent circuitmodels of components. Models generated with CoSeMod provide in many cases ashigh a quality as original (static) models do. One feature of scalability isthat new netlisting is not needed after component changes. The process ofmodel creation is based on similarities of the components of the same modelseries (packaging, manufacturing process, material etcetera). Requiredequations of the relationship between nominal and parasitic values arecalculated by nonlinear regression. Model generation for unknown componentsof a known series is possible with interpolation. Implementation is possiblewith relatively simple actions made in circuit simulator Saber. An EMCapplication example of the implemented model is also shown in this paper.
