ABSTRACT:
Methods for winding energy transfer element cores are disclosed. In one aspect, a method includes winding a plurality of layers of an input winding around an energy transfer element core. One layer of the input winding is wound with a number of turns different than a number of turns included in other layers of the input winding. An output winding is wound around the energy transfer element core with substantially the same number of turns as the number of turns of the one layer of the input winding to reduce substantially a capacitive displacement current flowing between the input and output windings.
