    • [0116] A multi- winding inductor includes a first foil winding and a second foil winding. One end of the first foil winding extends from a first side of the core and wraps under the core to form a solder tab under the core. One end of the second foil winding extends from a second side of the core and wraps under the core to form another solder tab under the core. Respective portions of each solder tab are laterally adjacent under the magnetic core. A coupled inductor includes a magnetic core including a first and a second end magnetic element and a plurality of connecting magnetic elements disposed between and connecting the first and second end magnetic elements. A respective first and second single turn foil winding is wound at least partially around each connecting magnetic element. Each foil winding has two ends forming respective solder tabs.

    • An M-winding coupled inductor (800) includes a first end magnetic element (802), a second end magnetic element (804), M connecting magnetic elements (902), and M windings (904). M is an integer greater than one. Each connecting magnetic element (902) is disposed between and connects the first (802) and second (804) end magnetic elements. Each winding (904) is wound at least partially around a respective one of the M connecting magnetic elements (902). The coupled inductor further includes at least one top magnetic element (806) adjacent to and extending at least partially over at least two of the M connecting magnetic elements to provide a magnetic flux path between the first and second end magnetic elements. The inductor may be included in an M-phase power supply, and the power supply may at least partially power a computer processor.
    • M绕组耦合电感器(800)包括第一端磁性元件(802),第二端磁性元件(804),M连接磁性元件(902)和M绕组(904)。 M是大于1的整数。 每个连接的磁性元件(902)设置在第一(802)和第二(804)端部磁性元件之间并连接其上。 每个绕组(904)至少部分地围绕M个连接磁性元件(902)中的相应一个缠绕。 耦合电感器还包括至少一个顶部磁性元件(806),其邻近并延伸至少两个M个连接磁性元件中的至少两个,以在第一和第二端部磁性元件之间提供磁通量。 电感器可以包括在M相电源中,并且电源可以至少部分地为计算机处理器供电。
