Abstract
A transformer includes a bobbin with spacers extending inwardly from the bobbin and a barrier extending outwardly from the bobbin. A ferrite core positioned within the bobbin is separated by the spacers to provide a controlled air gap. Primary windings wound around the bobbin are separated into series connected windings by the barrier. The barrier is aligned with spacers so as to prevent any wound portion of the primary windings from overlapping the air gap in the ferrite core.
