Abstract: An energy transfer element having an energy transfer element input winding, an energy transfer element output winding and energy transfer element windings that reduce displacement currents. In one aspect, an energy transfer elements includes an energy transfer element core with first and second windings wound around the energy transfer element core. The first winding is capacitively coupled to the second winding. A third winding is wound around the energy transfer element core to generate a third winding electrostatic field to substantially cancel relative electrostatic fields generated by the first and second windings relative to the energy transfer element core to substantially reduce a capacitive displacement current between the first and second windings. Fourth and fifth windings are wound around the energy transfer element core between the first and second windings to substantially reduce the capacitive displacement current between the first and second windings.

Abstract: A method of transferring energy is disclosed. In one aspect, a method includes transferring energy from a first winding wound around a transformer core to a second winding wound around the transformer core. The first and second windings capacitively coupled to electrical earth. The method further includes generating a third winding electrostatic field with a third winding wound around the transformer core and coupled to the first winding. A fourth winding electrostatic field is generated with a fourth winding wound around the transformer core and coupled to the second winding. The method also includes substantially reducing a capacitive displacement current between the first and second windings with the third and fourth electrostatic fields.
