Energy transfer elements having a shield to reduce EMI while maintaining a low profile are disclosed. In one example, the transformer may include a transverse shield wire that may be utilized to keep displacement current within the energy transfer element. While windings of the energy transfer element are generally wound axially around the axis of a bobbin in a direction generally perpendicular to the axis of the bobbin, the transverse shield wire may be placed on the bobbin extending over multiple power windings of the energy transfer element in a transverse direction. The transverse shield wire may be situated outside all other windings wound around the bobbin. In some examples, one end of the transverse shield wire may be coupled to a switching node of the energy transfer element while the other end of the transverse shield wire may be coupled to a winding of the energy transfer element.
