摘要： A cold plate and a method of manufacturing a cold plate involve a first side with a first surface, and a second side, opposite the first side, with a second surface opposite the first surface. The cold plate includes a flow channel formed between the first side and the second side, and a cavity integrally machined into the first surface of the first side. The cavity seats an inductor and is defined by an outer wall and a base with thicker sections and thinner sections such that even the thicker sections of the base are thinner than a thickness of the first surface.

摘要： An edge mount magnetic component includes a bobbin and two E-core halves. The bobbin is configured to receive the two E-core halves when body portions of the two E-core halves are positioned vertically. The bobbin includes a first outer flange, a second outer flange, and a passageway spanning therebetween. The bobbin further includes first, second, third, and fourth pin supports. The first and second pin supports are connected to an outer surface of the first end flange and are spaced apart by at least a width of the passageway. The third and fourth pin supports are connected to an outer surface of the second end flange and are spaced apart by at least the width of the passageway. The bobbin further includes slots for routing a winding to a pin and includes walls to ensure the winding is electrically separated from the E-core halves.

摘要： A power system has a power-electronic module that includes a housing defining a looped reservoir, a ferro-magnetic medium sealed within and filling the looped reservoir, and a conductor surrounded by the ferro-magnetic medium. The conductor is coiled within and along the looped reservoir, and has terminals extending out of the reservoir such that the ferro-magnetic medium and conductor form an inductor that opposes changes in magnitude of current flowing through the conductor.
