PURPOSE:To decrease the number of components and to prevent heat generation due to the core loss, by substituting the function of a size coil and a linear coil with only a saturable reactor with less core loss. CONSTITUTION:The saturable reactor performing the inductance control due to a DC current control and a magnet is provided between a deflection yoke 4 and a correcting capacitor 7. The current value of a horizontal deflection current flowing to the reactor 11 is corrected with the electric characteristic of the reactor 11. The reactor 11 used for this circuit is provided with the following two operating functions: (1), The inductance of the reactor 11 is changed with a resistor 12 or a voltage applied to the resistor 12 to control the horizontal deflection current (size variable). (2), The reactor 11 is provided with a permanent magnet, the magnetic characteristics of the reactor are changed by applying a magnetic bias with the permanent magnet to perform S-shaped control of the horizontal deflection current. Thus, the linearity of the horizontal deflection current is kept excellently. |
