    摘要: A method and apparatus for multi-phase transformers are described. In one embodiment, a coupled inductor topology for the multi-phase transformers comprising N primary inductors. In one embodiment, each primary inductor is coupled to one of N input nodes and a common output node. The transformer further includes N−1 secondary inductors coupled in series between one input node and the common output node. In one embodiment, the N−1 secondary inductors are arranged to couple energy from N−1 of the primary inductors to provide a common node voltage as an average of N input node voltages, wherein N is an integer greater than two. Other embodiments are described and claimed.

    摘要: A method and apparatus is described according to various embodiments, for flowing current from one region of a coil to another region of the coil. The flowing induces—through flux linkage —a voltage across a second coil. A second current substantially does not flow though the second coil. The method and apparatus also includes measuring the current with the voltage between the two coils.
