A method for winding an energy transfer element, the method comprising:
- winding a plurality of input layers of an input winding around an energy transfer element core between a first end and a second end of the input winding, wherein an outer layer of the plurality of layers of the input winding is wound with a number turns different than the number of turns in substantially each of the inner layers of the plurality of layers of the input winding;
- and
- winding a layer of an output winding around the energy transfer element core with substantially the same number of turns as the number of turns of the outer layer of the plurality of layers of the input winding to reduce substantially a capacitive displacement current flowing between the input and output windings.
