Abstract

PURPOSE:To prevent any deflected magnetization of the iron core of a transformer by changing the initial oscillation frequency of a given period from a frequency higher than the normal oscillation frequency to the normal oscillation frequency. CONSTITUTION:When a pulse voltage (e) corresponding to the X-ray exposure time is input, a capacitor (C1) is charged at a given time constant, and the input is sent into a comparator (1a). On the other hand, a pulse voltage (a) is input into the reset terminal of a flip-flop FF (2a), the FF (2a) is reset, and a capacitor (C2) starts to oscillate. Then, a pulse voltage (C) with a frequency synchronized with the frequency of the oscillation of the capacitor (C2) is input through a buffer 3 into a FF (2b). The frequency of the oscillation of the pulse voltage (C) becomes constant (a). The input voltage of the pulse voltage (C) is outputted by means of the FF (2b) so that a commutation capacitor (C3) and transistors (Tr1) and (Tr2) of an inverter circuit (I) are operated alternately. An inverter output voltage (Vp) is increased with a transformer 4, is rectified with a rectifier circuit 5, and the output voltage (VT) is applied to an X-ray tube.
