Zusammenfassung, Abstract
Within an initiative of different scientific and industrial partners a comparison of measurement analytical and numerical methods for core losses is conducted. Consequently a core evaluation kit was developed and used in different parts of the world to evaluate the effects of size shapes and measurement practices on the core loss models that we use for power conversions systems. In this paper the fluxometric four-wire characterisation method was used to characterise ferrite and nanocrystalline materials using different sizes flux densities supply voltages and switching frequencies. It was found that using the same magnetic material magnetic components have different iron loss properties when the size of the core is changed. These results are the very first of many procedures and tests with this initiative of the magnetic core evaluation kit. And it is expected to contribute to have a common and better understanding of core/iron losses of magnetic components in power electronics.
