Abstract

A power generator drives a rotating anode of an X-ray tube via a stator-rotor in which the stator receives the anode side high voltage potential. An isolating transformer is connected to an alternating current source which converts DC voltage to AC voltage via a rectifier bridge, a regulator and a switching inverter. The secondary winding of the isolating transformer is coupled to a second rectifier bridge for applying rectified voltage to a second switching inverter that generates the alternating currents for the stator windings. The second inverter receives the high voltage which is also applied to the tube to generate X-rays.
