IEC 62433-1:2019

EMC IC modelling - Part 1: General modelling framework

IEC 62433-1:2019 specifies the framework and methodology for EMC IC macro-modelling. Terms that are commonly used in IEC 62433 (all parts), different modelling approaches, requirements and data-exchange format for each model category that is standardized in this series are defined in this document.
IEC 62433-1 cancels and replaces IEC TS 62433-1 published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC TS 62433 1:2011:
Incorporation of a data exchange format for an integrated circuit’s model representation.
The contents of the corrigendum of July 2020 have been included in this copy.

Modèles de circuits intégrés pour la CEM - Partie 1: Cadre de modèle général

L'IEC 62433-1:2019 spécifie le cadre et la méthodologie pour des macromodèles de circuits intégrés pour la CEM (EMC IC). Les termes couramment utilisés dans l'IEC 62433 (toutes les parties), différentes approches pour la modélisation, des exigences et un format d’échange de données pour chaque catégorie de modèle normalisée dans cette série sont définis dans le présent document.
L’IEC 62433-1 annule et remplace l’IEC TS 62433-1 parue en 2011. Cette édition constitue une révision technique.
L'IEC 62433-1 inclut les modifications techniques majeures suivantes par rapport à l'IEC TS 62433-1:2011:
– Introduction d’un format d’échange de données pour la représentation d’un modèle de circuit intégré
