Abstract
A high-voltage generating circuit for use in a CRT display apparatus has a horizontal drive circuit which is supplied with a horizontal frequency signal synchronous with a horizontal synchronizing signal in an input signal, a high-voltage converter output circuit which can be turned on and off by an output signal from the horizontal drive circuit, and a flyback transformer connected to an output terminal of the high-voltage converter output circuit. A frequency multiplier connected between the horizontal drive circuit and a terminal supplying the horizontal frequency signal to the horizontal drive circuit multiples the frequency of the horizontal signal at the terminal by a multiplication factor variable depending on the frequency of the horizontal frequency signal.
