  • Patent number: 9865392
    Abstract: A series stacked, solenoidally wound, multipath inductor includes a plurality of turns disposed about a center region on two layers. The turns on the two layers have corresponding geometry therebetween. Each of the plurality of turns includes two or more segments that extend length-wise along the turns. The segments have positions that vary from an innermost position relative to the center region and an outermost position relative to the center region. A cross-over architecture is configured to couple the segments of a turn on one layer with the segments on a turn on another layer to form segment paths that have a substantially same length for all segment paths in a segment path grouping between the two layers.
