Abstract
A transformer providing low output voltage. A transformer core has two outer leg portions and a center portion. A primary winding has a first portion looped around one of the legs so that a current passed through the first winding will produce a magnetic flux in that leg that circulates in either the right hand or left hand sense. A second portion of the input signal winding is looped around the other leg in the opposite sense. This provides for a magnetic flux circulating through the two outer leg portions in the same sense, and provides that the magnetic flux circulating through the center portion is zero. The secondary winding is preferably provided as a fractional loop around one of the outer legs.
