Abstract

PURPOSE:To correct the misconvergence, by setting a control winding and a winding to be controlled to two saturable transformers to which a DC bias magnetic field is applied and connecting the winding to be controlled to a horizontal deflecting coil to supply the vertical deflecting current to the control winding. CONSTITUTION:The control windings 10a and 10b plus windings 13a and 13b to be controlled are provided to saturable transformers 7a and 7b respectively, and at the same time a DC bias magnetic field is applied to these transformers by permanent magnets 9a and 9b. The windings 10a and 10b are connected in series to each other in order to produce the magnetic fields of the polarities opposite to each other to be connected to bridge circuits 25, 26 and 27 to which the vertical deflecting current flows. Then horizontal deflecting coils 1a and 1b are connected in series to the windings 13a and 13b respectively. The inductances of the windings to be controlled vary in opposite direction to each other by the level and the polarity of the current which is supplied to the control windings. As a result, the amount of correction can be modulated for the cross misconvergence with the vertical diflecting current.
