    Abstract: Energy transfer element circuitry for use in a power converter includes a cancellation shield winding wound around an energy transfer element core. A first trimming capacitor is coupled to a first end of the cancellation shield winding to adjust a shield response of the cancellation shield winding. A second end of the cancellation shield winding is unconnected. A primary winding is wound around the energy transfer element core. A balance shield winding is wound around the energy transfer element core. A second trimming capacitor is coupled to a second end of the balance shield winding to adjust a shield response of the cancellation shield winding. A first end of the balance shield winding is unconnected. A secondary winding is wound around the energy transfer element core.
