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.
