ABSTRACT:
In an exemplary embodiment a direct-current supply with adjustable d.c. voltage supplies an inverter which in turn drives the high-tension transformer. High-tension capacitors are connected at the output of the high-tension rectifier, and control loops are provided for the x-ray tube voltage and the x-ray tube current. The controlled variable is the inverter frequency in the control loop for the x-ray tube voltage. There is a program storage in which an optimum d.c. voltage for the inverter input is programmed for each pair of settings of x-ray tube voltage and current. There can be a function generator present which before the start of the radiograph supplies a control signal corresponding to an inverter input voltage lying a predetermined amount above the respective programmed value. The inverter input voltage may be regulated by a feedback control loop, and the set point value from program storage may be temporarily increased by the function generator at the start of a radiograph.
