Cores made of soft magnetic materials - Measuring methods - Part 3: Magnetic properties at high excitation level (IEC 62044-3:2000)
V tem standardu so predstavljene 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 za aplikacije močnostne elektronike Metode, podane v tem standardu, 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 standardu 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 danim valovnim oblikam indukcije in 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 predpisanimi izračuni, ki so za takšne materiale običajna. Ta načela so navedena v standardu IEC 60404-8-6.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the
two organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62044-3 has been prepared by IEC technical committee 51:
Magnetic components and ferrite materials.
The text of this standard is based on the following documents:
FDIS Report on voting
51/573/FDIS 51/583/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
Annexes A, B, C, D, and E are for information only.
IEC 62044, presented under the general title Cores made of soft magnetic materials –
Measuring methods, will include the following parts:
Part 1: Generic specification (under consideration)
Part 2: Magnetic properties at low excitation level (under consideration)
Part 3: Magnetic properties at high excitation level
Part 4: Non-magnetic properties (under consideration)

Part 3 is the first to be published. IEC 60367-1 and IEC 60367-2 will be cancelled after parts
1, 2 and 3 of IEC 62044 are published.
This standard cancels and replaces 11.2 and annex J of IEC 60367-1. The remaining clauses
of IEC 60367-1 will be replaced by IEC 62044-1 and IEC 62044-2.
The committee has decided that the contents of this publication will remain unchanged
until 2006. At this date, the publication will be
reconfirmed;
withdrawn;
replaced by a revised edition, or
amended.

Part 3: Magnetic properties at high excitation level
1 Scope
This standard provides 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 standard can cover the measurement of magnetic properties for
frequencies ranging practically from d.c. 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 standard ar
