In an illustrative embodiment, a high voltage transformer has a high voltage rectifier and an x-ray tube connected thereto, in which a switch and control tube lies in the x-ray tube circuit, a control installation supplying to a control grid of the switch and control tube, a voltage determining the voltage of the x-ray tube. A semiconductor switching arrangement with ignition characteristic is in series with the switch and control tube and has a control stage which delivers an ignition signal for the engagement of the x-ray tube.
