  • Low stray-loss transformers and methods of assembling the same
    Patent number: 10153085
    Abstract: A transformer includes a magnetic core, a first winding assembly inductively coupled to the magnetic core, and a second winding assembly inductively coupled to the first winding assembly. The magnetic core includes a winding leg. The first winding assembly includes a plurality of first layers, and the second winding assembly includes a plurality of second layers. The first and second winding assemblies are concentrically wound around the winding leg in an interleaved configuration, where at least one of the plurality of second layers is disposed between two of the plurality of first layers, and at least one of the plurality of first layers is disposed between two of the plurality of second layers.
    Type: Grant

  • Low stray-loss transformers and methods of assembling the same
    Patent number: 9640315
    Abstract: A transformer includes a magnetic core, a first winding assembly, and a second winding assembly. The magnetic core includes a plurality of legs, including a first winding leg. The first winding assembly includes a first conductive conduit helically wound around the first winding leg a first number of turns. The first winding assembly has a first magnetic length. The second winding assembly includes a second conductive conduit wound around one of the plurality of legs a second number of turns. The second winding assembly is inductively coupled to the first winding assembly, and has a second magnetic length substantially equal to said first magnetic length.
