Title: High voltage control circuit
Inventor: TOMINAGA KIYONORI
IPC: H04N3/18
Filed: 1984-02-13
Abstract: PURPOSE:To obtain an excellent high voltage with simple constitution by controlling the timing of the switching element ON at the latter half of a drive pulse period so as to obtain the regulated high voltage from a secondary coil of a flyback transformer. CONSTITUTION:The high voltage control is performed by controlling a drive phase of a switching element 11. That is, when the element 11 is driven at the latter half of the trace period, a current i2 starts flowing in a primary coil 12a of the flyback transformer 12 and when the element 11 is turned off at the latter half of the retrace period, no current flows to the primary coil during the period from a point of time when the current flowed in the primary coil 12a is zeroed until the next on-drive is applied. In decreasing the conductive period of the element 11 and a diode 9, a voltage across a coupling capacitor 6 is increased and the higher it becomes, the lower the high voltage generated in the secondary coil 12b of the flyback transformer 12 becomes. Thus, the high voltage is controlled by changing the phase of the on-drive.
