The " classic " shape of a magnetic circuit made of nanocrys-talline alloy is usually the toroidal one. In power electronics, this shape is not the best one in terms of size and congestion. For high power magnetic components, the UU or CC shape is preferred. Recently two manufacturers have commercialized new magnetic circuits made of nanocrystalline alloy in this last shape. But before using these new products in power electronics, we have, first to know them well and to be sure that they will respond adequately to the peculiar needs of the application. In this paper, we compare several cut cores geometric dimensions and magnetic properties from two different manufacturers. Full amplitude characterisations are performed. The dispersions of the samples and the agreement to datasheets are presented.
