Reconfiguring tape wound cores for inductors

摘要

A tape wound inductor core device, inductors including same and methods of manufacture. Tape wound material may be cut and/or shaped into “pucks” that have an exterior surface made up of or defined substantially by the edge surfaces of the layers of the constituent conductive material, with all or most of the broad surfaces disposed inwardly, thereby reducing eddy currents and associated losses. Various puck configurations, inductor arrangements and fabrication techniques are disclosed.

主权项

1. A tape wound inductor core device, comprising:
a first core puck that is a segment of reconfigured tape wound core and includes alternating layers of conductive material and insulative material, the conductive material layers each having a broad surface and an edge surface, wherein the broad surface is the surface with the greater dimension across the layer and the edge surface is located at the edge of the broad surface; and wherein the plurality of conductive material layers are reconfigured within the tape wound puck such that the exterior surface of the puck is defined substantially by edge surfaces and the broad surfaces are situated substantially interiorly within the puck so as to not be exposed substantially on the exterior of the puck.
