HORIZONTALLY DEFLECTING HIGH VOLTAGE CIRCUIT

摘要

PURPOSE:To solve the unbalance of a horizontal size by connecting an AC component removing capacitor to the base of the transistor for a horizontal center circuit of the horizontal center circuit and increasing the inductance of a choke coil for a horizontal center. CONSTITUTION:The change of base voltage is reduced by connecting an AC component removing capacitor 17 to the junction between the bases of transistors 14 and 15 for the horizontal center of a horizontal center circuit 23 and capacitors 19 and 20 and grounding the bases of the transistors 14 and 15 for the horizontal center in an AC manner. Further, impedance for an alternating current is increased by setting the inductance of a choke coil 11 for the horizontal center to 3mH or above. Thus, the AC component of a horizontal center current can be removed, and the unbalance between size fluctuation quantity at a right side and that at a left side can be eliminated.
