Inductor systems using flux concentrator structures

摘要

An apparatus (e.g., an inductor system) includes an elongate magnetic core, at least one coil wrapped around the magnetic core and a spacer configured to separate an inner side of the at least one coil from the magnetic core to provide a coolant passage between the inner side of the at least one coil and the magnetic core. The apparatus further includes at least one flux concentrator body positioned on an outer side of the at least one coil and configured to concentrate a magnetic flux on the outer side of the at least one coil. In some embodiments, the apparatus includes a frame configured to support the magnetic core, the at least one coil and the at least one flux concentrator body. In further embodiments, the at least one flux concentrator body may be mounted on at least one wall of an enclosure or chassis.

主权项

1. An apparatus comprising:
a bar of magnetic material; at least one coil wrapped around the bar of magnetic material; a spacer spacing an inner side of the at least one coil apart from the bar of magnetic material such that a coolant passage exposing the inner side of the at least one coil and an outer surface of the bar of magnetic material is disposed between the inner side of the at least one coil and the bar of magnetic material; and at least one mass of magnetic material positioned on an outer side of the at least one coil so as to not overlap ends of the bar of magnetic material, wherein the at least one mass of magnetic material is not surrounded by another coil.
