ABSTRACT:
A fluxbucking line transformer is disclosed in which fluxbucking primary windings in the line transformer compensate for the DC flux generated by the passing of DC currents by the primary windings. No feed-back circuitry is required for sensing the DC components of the magnetic field in the transformer core or to sense the DC current through the transformer to provide adjustment of the fluxbucking current. The disclosed transformer circuit is a bridge configuration which cancels the DC flux independently in separate primary windings, and is advantageously employed in telephone line circuits in which large DC currents are passed through the line transformer while smaller ac signals are coupled to the secondary without distortion of the ac signals due to saturation of the transformer core.
