A vehicle, an inductor assembly for power electronics in a vehicle, and a method of providing and cooling an inductor assembly are provided. According to one example, the vehicle is provided with an inductor assembly in a vehicle electrical system with a variable voltage converter (VVC). The inductor assembly includes a core formed from a plurality of core segments spaced apart from one another to define gaps therebetween, with each of the plurality of core segments forming an internal fluid passage extending therethrough. The inductor assembly has a winding surrounding at least one of the plurality of core segments. A fluid system is connected to the core to provide pressurized fluid to the fluid passages of the plurality of core segments to circulate fluid through the core of the inductor assembly.

An electro-magnetic coil with coolant permeability wound using insulated wire includes a plurality of radially arranged layers and a plurality of axially arranged turns of the insulated wire per layer, wherein the insulated wire has a plurality of sections along its length with different cross-sections for any pair of two adjacent sections that collectively form into axial and radial coolant channels as the wire is wound around a core.
