PROBLEM TO BE SOLVED: To reduce a correction current to reduce the breakdown strength and the current rating of an element. SOLUTION: A damper diode 2 and a resonance capacitor 3 are provided in parallel with a horizontal switching element, and a series circuit consisting of a horizontal deflecting coil 4 constituting a deflecting yoke and a DC cutting- off capacitor 5 is provided. When the horizontal switching element 1 is turned on by, for example, a horizontal synchronizing signal, a horizontal deflecting saw-tooth current is caused to flow to the horizontal deflecting coil 4 by the action of the damper diode 2 and the resonance capacitor 3. A secondary winding 6 is provided which is wound while being insulated from the horizontal deflecting coil 4. A series circuit of a capacitor 7 and a coil 8 is connected in parallel to this secondary winding 6. The inductance value and the capacity value of these capacitor 7 and coil 8 are controlled. |
