标准摘要
[中文适用范围]： 本部分 IEC 62044 规定了用于功率电子应用的电感器、扼流圈、变压器和类似器件中形成闭合磁路的磁芯的功率损耗和振幅磁导率的测量方法。本文档中给出的方法可以覆盖从直流到 10 MHz 甚至更高的频率范围内的磁性测量，具体取决于所需精度水平。本文档中的方法最适合正弦波激励，但也可以使用其他周期性波形，只要测量电路和仪器能够处理相应频谱内的信号幅度和相位，且精度仅略有下降。 [外文原描述]： IEC 62044-3:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62044-3:2023 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. This second edition cancels and replaces the first edition published in 2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: addition of Annex F and Annex G.
