<p>PURPOSE:To restrain high voltage load fluctuation and reduce amplitude change of an image plane, by connecting a load fluctuation restraining resistor across the winding start of l secondary high voltage winding of a specific layer counted from the low voltage side of the secondary high voltage winding and the cathode of a rectifier diode of the secondary high voltage winding. CONSTITUTION:When (n) is an odd number in a secondary high voltage winding (n), a load fluctuation restraining resistor 19 Ls connected across the winding start of the coil of the layer being (n+1)/2 and the cathode of a rectifier diode of the layer. When (n) is an even number, the resistor 19 is connected across the winding start of the coil of the layer being an n/2 layer and the cathode of the rectifier diode of the layer. When (n) is an odd number, a focus volume block 12 is connected across the cathode of a rectifier diode connected with the winding end of a coil being (n+1)/2 and the earth 21. When (n) is an even number, the focus volume block 12 is connected across the cathode of the rectifier diode connected with the winding end of a coil of the layer being an n/2 layer and the earth 21.</p> |
