Abstract
A horizontal deflection winding centering circuit includes a Darlington transistor and a diode. The Darlington transistor and diode form a non-linear network that is coupled in series with an inductor. The series arrangement of inductor and non-linear network is coupled in parallel with a horizontal deflection winding. The base voltage of the Darlington transistor is produced by a voltage divider coupled in a current path of the inductor current.
