    Abstract: The present embodiment relates to a DC-DC converter comprising: a housing; a plurality of electronic components disposed inside the housing; and a flow path disposed on a lower plate of the housing. The flow path comprises an expanding portion. The horizontal width of the expanding portion is greater than the horizontal width of a flow path on the front end of the expanding portion, and the vertical width of the expanding portion is less than the vertical width of the flow path on the front end of the expanding portion. The differential between the part wherein the surface area of the vertical cross section of the flow path is the biggest and the part wherein the surface area of the vertical cross section of the flow path is the smallest is 10% or less.

    Abstract: Disclosed are a soft magnetic alloy and a wireless charging apparatus including the soft magnetic alloy. The soft magnetic alloy has a chemical formula expressed as Fe100−x−yCuxBy (wherein x ranges from 0.1 at % to 1.7 at % and y ranges from 2.3 at % to 9.6 at %). Without adding any expensive alloying element, only iron (Fe), copper (Cu), and boron (B) are used to obtain a nanocrystalline soft magnetic alloy that has a low coercive force and a high saturation magnetic flux density. The nanocrystalline soft magnetic alloy is applied to a wireless power transmitter and a wireless power receiver. Thereby, it is possible to make a shield member thin and increase a power transmission capacity. The soft magnetic alloy is easily processed into a flake form. The soft magnetic alloy processed in this way is applied to the shield member. Thereby, it is possible to increase permeability in a surface direction.
