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.
Claims20
A transformer comprising:
- a magnetic core comprising a plurality of legs including a first winding leg;
- a first winding assembly comprising a first conductive conduit helically wound around said first winding leg a first number of turns, said first winding assembly having a first magnetic length;
- and
- a second winding assembly inductively coupled to said first winding assembly, said second winding assembly comprising a second conductive conduit wound around one of the plurality of legs a second number of turns, said second winding assembly having a second magnetic length substantially equal to said first magnetic length.
A transformer comprising:
- a magnetic core comprising a winding leg;
- a first winding assembly comprising a plurality of first layers, said first winding assembly inductively coupled to said magnetic core;
- and
- a second winding assembly inductively coupled to said first winding assembly, said second winding assembly comprising a plurality of second layers, wherein said first and second winding assemblies are concentrically wound around said winding leg in an interleaved configuration, wherein each second layer is disposed between at least two adjacent first layers.
A method of assembling a transformer, said method comprising:
- providing a magnetic core including a plurality of legs including a first winding leg;
- providing a first winding assembly including a first conductive conduit;
- providing a second winding assembly including a second conductive conduit;
- inductively coupling the first winding assembly to the magnetic core by helically winding the first conductive conduit around the first winding leg a first number of turns such that the first winding assembly has a first magnetic length;
- and
- inductively coupling the second winding assembly to the first winding assembly by winding the second conductive conduit around one leg of the plurality of legs a second number of turns such that the second winding assembly has a second magnetic length substantially equal to the first magnetic length.
A method of assembling a transformer, said method comprising:
