Abstract
The high voltage generating apparatus includes a flyback transformer to be employed in television equipment and has a circuit for stabilizing a high voltage output. This circuit comprises an additive voltage generating coil, a reference voltage generating circuit, a voltage detector, a comparison amplifier, a switching circuit and a voltage multiplying rectifier circuit. The reference voltage generating circuit generates an inclined voltage in the flyback time of the horizontal deflection cycle and the voltage detector detects a mode of the high voltage output. The comparison amplifier compares an inclined voltage and a detection voltage and generates a control signal. The switching circuit operates with the control signal. With this operation, an additive voltage generated by the additive voltage generating coil is supplied to the high voltage coil of the flyback transformer through the voltage multiplying rectifier circuit. The voltage to be supplied compensates the voltage fall if the high voltage output and accordingly the high voltage output is stabilized.
