Abstract:
1. An energy transfer element, comprising: an energy transfer element core; a first winding wound around the energy transfer element core; a second winding wound around the energy transfer element core, the first winding capacitively coupled to the second winding; a third winding wound around the energy transfer element core, the third winding 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; and a fourth winding and a fifth winding 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, the fourth winding coupled to the first winding and the fifth winding coupled to the second winding.
