Abstract

The invention provides a novel design of transformer having a bobbin formed in two parts which may have their windings wound separately. The design also incorporates an EMI shield formed within the bobbin to provide EMI shielding between the windings on each of the bobbin halves. The transformer may also include a divider to provide improved electrical isolation of the windings and between the windings and the magnetic core of the transformer.
