发明名称 Method and apparatus for substantially reducing electrical displacement current flow between input and output windings of an energy transfer element
摘要 An energy transfer element with substantially reduced electrical displacement current flow between an input circuit coupled to the energy transfer element input winding and an output circuit coupled to the energy transfer element output winding. In one aspect, an energy transfer element includes an input winding, an output winding, an electrically conductive shield coupled to the input winding and a first cancellation winding coupled to the input winding. The electrically conductive shield is physically positioned between input and output windings. The output winding is physically positioned between the electrically conductive shield and the first cancellation winding. The first cancellation winding is wound to substantially reduce a capacitive displacement current between the input circuit and the output circuit.
