Abstract
An X-ray generator for operating an X-ray tube having parts of the tube connected to ground includes a high-voltage transformer arrangement having distinct secondary windings for producing positive and negative high voltages, for the anode and the cathode, respectively, of the X-ray tube. The unfavorable voltage distribution inherent in the feeding of such an X-ray tube by a high-ohmic generator is removed in a simple manner in that the secondary windings are each associated with a primary winding and that in series with the primary winding for producing the anode voltage an inductance is connected by means of a switching device.
