  • INDUCTOR MOUNTING, TEMPERATURE CONTROL, AND FILTERING METHOD AND APPARATUS
    Publication number: 20090045898
    Abstract: Methods and apparatus according to various aspects of the present invention may be implemented in conjunction with a inductor mount mounting to a mounting surface. The inductor mount may comprise an inductor having a center opening, and a surface area encompassing all of a front face, a back face, an inner surface about the center opening, and an outer edge concentric about the center opening. The inductor mount may further include mounting hardware holding the outer edge of then inductor to the mounting surface. A cooling element moves air into contact with the front face, through the center opening, and around the outer edge of the inductor. In various embodiments, the mounting hardware contacts less that ten percent of the surface area of the inductor.
