ABSTRACT:
There is disclosed a circuit for stablizing the high voltage of the high voltage generating circuit in a CRT according to the change of the horizontal oscillating frequency, comprising a diode, the cathode of said diode being connected to the intermediate terminal of a flyback transformer (FBT), the anode of said diode being connected to first resistor and a variable resistor, a first transistor, the base of the said first transistor being connected to the intermediate terminal of said variable resistor, a second transistor, a third transistor, the collector of said first transistor being connected through a grounded second resistor to the base of said third transistor, the collector of said third transistor being connected to the base of said second transistor, the collector of said second transistor being connected to a direct current source, and a fourth transistor, the emitter of said second transistor being connected through the primary coil of said flyback transformer to the collector of said fourth transistor, the base of said fourth transistor being connected to a horizontal oscillating circuit.
