“…A similar approach is used in electric machines. The laminations at the edge of the core are sectioned to reduce the eddy current losses as shown in [24]. Following a similar approach, the lateral walls of the nanocrystalline ribbon cores can be segmented with cuts along the x and y axes.…”

“…k, α, β, and γ are material-dependent constants. Values of the constants for Finemet material operating at high frequencies were determined by FEA in [16,21], and the values used in this paper are k= 1.6810 -3 , = 1.72, = 2 and = 1.65 [16].…”

“…One way to reduce the hot spots in the core is through the use of high-thermal-conductivity heat spreaders placed around the gap [18], for example using aluminum nitride. Further, a number of methods have been proposed to reduce gap losses including the use of multiple smaller gaps around the magnetic circuit [19], cutting slits in the cores near the air gap [20], or splitting the core into several sub-cores placed side-by-side [21]. More complex sub-sectioning of the core has also been proposed [22].…”

“…To reduce the overall inductor losses, two techniques are implemented: split-cores to lower the gap losses [14], and dual-foil windings to tackle the high-frequency losses in the conductors [15].…”
