Abstract: In a horizontal deflection circuit including a switch for coupling an energy source to a deflection yoke and for inducing alternating current in an output transformer, two horizontal deflection coils are serially coupled between the energy source and a point of reference potential and a winding of the output transformer is serially coupled between the two deflection coils and poled in the circuit such that the retrace pulse component developed in the winding opposes the retrace pulse developed across the coils for reducing the total pulse voltage across the coils.
