Abstract: 

The “constant-flux inductors” are developed to achieve high magnetic-energy density, leading to significantly lower height than that of conventional products. Techniques to shape the core and to distribute the winding turns to shape a desirable field profile are described for the surface-mount inductors. A relatively constant flux distribution is advantageous not only from the density standpoint, but also from the thermal standpoint via the reduction of hot spots, and from the reliability standpoint via the suppression of flux crowding. Prototype cores and windings were routed from powder-iron disks and copper sheets, respectively. The design of constant-flux inductor was validated by the assembled inductor prototype.
