ABSTRACT:
An X-ray generating apparatus is adapted to obtain an X-ray tube voltage by rectifying an incoming AC voltage to obtain a DC voltage, supplying the DC voltage, after being switched through a switching section, in a predetermined cycle to a resonance circuit comprised of a primary winding of a transformer and resonance capacitors and rectifying the AC voltage which is induced in the secondary winding of the transformer. The switching section comprises a three-phase bridge inverter circuit including parallel arrays of arms each of which is made up of a pair of switching elements. The switching section is so controlled that the switching elements in each respective arm are fired without being continuously turned ON. Each resonance capacitor is connected between an intermediate connection point of the respective arm of the switching section and the primary winding of the transformer.
