High efficiency thin film inductor |
摘要 |
An improved thin film inductor design is described. A spiral geometry is used to which has been added a core of high permeability material located at the center of the spiral. If the high permeability material is a conductor, care must be taken to avoid any contact between the core and the spiral. If-a dielectric ferromagnetic material is used, this constraint is removed from the design. Several other embodiments are shown in which, in addition to the high permeability core, provide low reluctance paths for the structure. In one case this takes the form of a frame of ferromagnetic material surrounding the spiral while in a second case it has the form of a hollow square located directly above the spiral.
