Cores made of soft magnetic materials - Measuring methods - Part 3: Magnetic properties at high excitation level

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 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 induction and field strength waveforms with only slightly degraded accuracy.
