Cores made of soft magnetic materials - Measuring methods - Part 3: Magnetic properties at high excitation level
This part of IEC 62044 specifies measuring methods for power loss and amplitude permeability
of magnetic cores forming the closed magnetic circuits intended for use at high excitation levels
in inductors, chokes, transformers and similar devices for power electronics applications.
The methods given in this document can cover the measurement of magnetic properties for
frequencies ranging practically from direct current to 10 MHz, and even possibly higher, for the
calorimetric and reflection methods. The applicability of the individual methods to specific
frequency ranges is dependent on the level of accuracy that is to be obtained.
The methods in this document are basically the most suitable for sine-wave excitations. Other
periodic waveforms can also be used; however, adequate accuracy can only be obtained if the
measuring circuitry and instruments used are able to handle and process the amplitudes and
phases of the signals involved within the frequency spectrum corresponding to the given
magnetic flux density and field strength waveforms with only slightly degraded accuracy.
NOTE It can be necessary for some magnetically soft metallic materials to follow specific general principles,
customary for these materials, related to the preparation of specimens and specified calculations. These principles
are formulated in IEC 60404-8-6.

IEC 62044-3:2023 est disponible sous forme de IEC 62044-3:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L'IEC 62044-3:2023 spécifie les méthodes de mesure de la perte de puissance et de la perméabilité d'amplitude des noyaux magnétiques qui forment les circuits magnétiques fermés destinés à être utilisés à des niveaux élevés d'excitation dans les bobines d'inductance, les bobines d'arrêt, les transformateurs et les dispositifs similaires pour les applications d'électronique de puissance. Cette deuxième édition annule et remplace la première édition parue en 2000. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: ajout de l'Annexe F et de l'Annexe G.
Jedra iz mehkomagnetnih materialov - Merilne metode - 3. del: Magnetne lastnosti pri močnem vzbujanju
V tem delu standarda IEC 62044 so določene merilne metode za izgubo moči in amplitudno prepustnost magnetnih jeder, ki tvorijo zaprta magnetna vezja, namenjena za uporabo pri močnem vzbujanju v induktorjih, dušilkah, transformatorjih in podobnih napravah z močnostno elektroniko.
Metode, podane v tem dokumentu, lahko zajemajo merjenje magnetnih lastnosti za frekvence v območju od enosmernega toka do 10 MHz in morda še celo več, za kalorimetrične in odbojne metode. Uporabnost posameznih metod za določena frekvenčna območja je odvisna od stopnje natančnosti, ki jo je treba doseči.
Metode v tem dokumentu so v osnovi najprimernejše za sinusno vzbujanje. Uporabiti je mogoče tudi druge periodične valovne oblike, vendar zadostno natančnost je mogoče doseči le, če so uporabljena merilna vezja in instrumenti zmožni obravnavati ter obdelati amplitude in faze signalov, vključene v frekvenčnem spektru, ki ustreza dani gostoti magnetnega pretoka in valovnim oblikam jakosti polja z le nekoliko manjšo natančnostjo.
OPOMBA: Za nekatere magnetno mehke kovinske materiale bo morda treba upoštevati posebna splošna načela v zvezi s pripravo primerkov in podanimi izračuni, ki so za takšne materiale običajna. Ta načela so navedena v standardu IEC 60404-8-6.
