Abstract: A power supply circuit for an x-ray production system, which has an inverter circuit with an output for connecting the inverter circuit with an x-ray source of the x-ray production system, includes a rectifier circuit including an input to connect the rectifier circuit with a power supply network, the rectifier circuit further including an output to connect to an input of the inverter circuit; and a backup circuit including a plurality of electrical energy storage cells, the plurality of electrical energy storage cells being connectable in series between the input of the inverter circuit and the output of the rectifier circuit.

Abstract: A method is for detecting high-voltage flashovers in X-ray equipment including an X-ray emitter and a high-voltage supply. The X-ray emitter has an X-ray tube, surrounded by an insulating medium; and the high-voltage supply has a high-voltage generator and a cable. The cable is at least part of a connecting passage between the high-voltage generator and the X-ray tube. During normal operation of the X-ray equipment, an interference pulse, which occurs due to the high-voltage flashover in the connecting passage, is detected and evaluated with the aid of a measuring device, including a measuring element. As such, an assessment of the condition of the X-ray emitter and of other high voltage-carrying components, and measures that follow, are made using the evaluated interference pulse.

Abstract: A computed tomography device includes a slipring for rotational transmission and a feed line. The slipring is arranged to be rotatable relative to the feed line. Two sliding contact elements are further included, forming sliding contacts between a slideway of the slipring and the feed line, the two sliding contacts being connected in parallel with one another and electrically conductively connected together via at least one portion of the slideway and via at least one portion of the feed line. Finally, the computed tomography device includes a measuring apparatus, configured to acquire a measured value dependent on a resultant inductance between the two sliding contact elements; and at least one processor, configured to determine an operating state of the two sliding contacts based upon the measured value.
