Test methods for electrical and magnetic properties of magnetic powder cores

This standard provides the test methods for the electrical and magnetic properties of magnetic powder cores used for inductive components in electronics equipment, switch-mode power supplies and power conversion equipment, and introduces measuring principles, scope of application and matters needing attention for each method. The parameters used to characterize the magnetic powder cores include: inductance factor, effective permeability, complex relative permeability, temperature coefficient of permeability, frequency coefficient of permeability, DC bias characteristic, power loss, and quality factor. This standard is the basis for determining the characteristic parameters of magnetic powder cores.

Méthodes d'essai des propriétés électriques et magnétiques des noyaux en poudre magnétique

L'IEC 63300:2023 fournit les méthodes d'essai des propriétés électriques et magnétiques des noyaux en poudre magnétique utilisés pour les composants inductifs des équipements électroniques, des alimentations à découpage et des équipements de conversion de puissance. Il décrit les principes de mesure, le domaine d'application et les points d'importance pour chaque méthode. Les paramètres utilisés pour caractériser les noyaux en poudre magnétique comprennent: le facteur d'inductance, la perméabilité effective, la perméabilité relative complexe, le coefficient de température de perméabilité, le coefficient de fréquence de perméabilité, la caractéristique de polarisation en courant continu, les pertes de puissance et le facteur de qualité. Le présent document sert de base pour la détermination des paramètres caractéristiques des noyaux en poudre magnétique.
