Resumen de Properties of coiled core made of cold rolled sheets with frequency up to 2000Hz
Andrzej Buze, Andrzej Krawczyk
Electrical properties of magnetic material are mainly defined by producers by means of magnetic characteristics H = ƒ(B) and loss characteristics p = ƒ(B), both for industry frequency, i.e. 50 or 60Hz. The curves defined in this manner are not compatible with those of higher frequency, i.e. far above 50Hz. The latter cases are of great importance when dealing with power electronics systems.
