Abstract Scope |
Reduction of losses during energy transformation is one of the main goals in the areas related to power electronics. Currently application of nanocrystalline soft magnetic materials like FINEMET allows the great reduction in core losses especially in the chokes coils, used mainly in the circuits, with the wide spectrum of high frequency harmonics.
Present state-of-the-art shows, that there is no comprehensive knowledge about the value of the magnetic flux density dispersion Bd on the gaps of nanocrystalline core and the possibilities of its minimization. The magnetic flux density dispersion Bd is the source of local eddy currents, which are the cause of increase of power loss.
A developed method for measuring the magnetic flux density dispersion Bd in the Fe73.5Si13.5B9Nb3Cu1 nanocrystalline cores with four gaps is presented together with the study of the effect of gap width and the method of its filling on the power losses in the core. |
