Abstract
A horizontal deflection circuit arrangement in which a saturable reactor operating as a variable impedance element is provided in the path of a horizontal deflection current flowing through a horizontal deflection coil for stabilizing the horizontal deflection current against fluctuations of the frequency of a horizontal drive signal for a horizontal output switching device, thereby to keep a suitable horizontal size of a raster made by the beam scan caused by the deflection current. The saturable reactor is supplied with a control signal varying in response to variations in the frequency of the horizontal drive signal to control the impedance thereof so as to compensate for the variations of the horizontal deflection current.
