Abstract
A low self-capacitance inductor is described for use as an output inductor in high frequency inverter power supplies. A pair of channel-shaped ferrite core members are assembled with a gap of material approximating the permeability of air. The core members are arranged to provide an axial aperture therebetween. A plurality of conductor segments are disposed in the aperture and are electrically interconnected to plated through holes in a supporting printed circuit board assembly. The conductor turns for the inductor are selected by the pattern of printed circuit interconnections between selected ones of the plated through holes, whereby the same current densities in the inductor are achieved for different conductor turns arrangements.
