Abstract: A high voltage generating device for an X-ray apparatus includes a DC output voltage control device for rectifying and smoothing a commercial AC power source voltage and a resonant circuit comprised of a series circuit of a capacitor and a primary winding of a transformer. The output DC voltage of the DC output voltage control device is supplied to the resonant circuit in a first direction or in a direction opposite to the first direction. The direction in which the voltage is applied to the resonant circuit is switched by a current switching means. Consequently, a high AC voltage is obtained through a secondary winding of the transformer. The AC voltage is converted by a rectifying/smoothing means to an X-ray tube voltage which is applied between an anode and a cathode filament of an X-ray tube. The DC output voltage control device permits its output voltage to be switched to an arbitrary level.
