ABSTRACT:
A high voltage stabilizing circuit includes: an error amplifier for receiving a flyback pulse rectified from one secondary side coil of a flyback transformer at an inverting terminal thereof and for receiving a reference voltage at a non-inverting terminal thereof, and for comparing the received inputs; a pulse width modulator for implementing a modulating operation in accordance with an output signal of the error amplifier and for simultaneously generating an output signal which is synchronous with the flyback pulse; a switching unit for performing a switching operation in accordance with the output signal of the pulse width modulator; and an auxiliary transformer having a primary side coil to which an output signal of the switching unit is supplied and a secondary side coil which is connected in parallel to another secondary side coil of the flyback transformer, for producing an output pulse corresponding to the flyback pulse outputted from the flyback transformer.
