ABSTRACT:
An inductor assembly is provided with turns of a coil conductor that encircle a leg of a magnetic core and are insulated from the core. Each of the turns includes a portion which extends through an aperture in the core and a second portion positioned outside the aperture. The surface area per unit length of the second portions of selected turns is greater than the surface area of the portions of the turns which extend through the aperture. These portions of increased surface area are spaced apart to permit the flow of cooling medium between the turns.
