Abstract

A transformer includes a first winding and a second winding coupled to the first winding through a magnetic circuit so that current through the first winding induces a voltage across the second winding. The first winding includes n separate shield portions, where n is an integer. Each of the n shield portions shields only a corresponding portion of the first winding. Each of the n shield portions is electrically coupled to the adjacent shield portion(s) substantially only through its coupling to the first winding, the first winding, and the other(s) of the adjacent shield portion's (s') coupling(s) to the first winding.
