Abstract: At least one shield member interposed between primary and secondary windings of a transformer and connected to the primary and/or secondary windings forms a distributed parasitic capacitance between the shield member and either the winding to which it is not connected or another shield member connected to that winding. Connections are made to the respective transformer windings such that the voltage distributions thus developed cause complementary common mode noise to be conducted in opposite directions in respective portions of the parasitic capacitance such that net common mode current can be made arbitrarily small without requiring that both sides of the distributed parasitic capacitance have complementary or equal voltage distributions. Such complementary common mode currents can be achieved by dividing opposing shield members or developing a voltage distribution in a single shield member in accordance with Faraday's Law.

Abstract: Technologies are generally described for switchable patterned metal shield inductance structures. In some examples, an inductance structure on a substrate may include an inductor and a metal shield, where the metal shield separates and shields the inductor from the substrate. The configuration of the metal shield and the inductor may facilitate reduction in the overall inductance of the inductance structure. In particular, the metal shield may be configured to develop one or more eddy currents in response to an inductor-generated magnetic field. The eddy currents may then result in a magnetic field opposing the inductor-generated magnetic field, which may result in a reduction in the overall magnetic field and the overall inductance of the inductance structure. The metal shield may be switchable between multiple modes, where each mode may be effective to reduce the overall inductance by a different amount.
