Abstract: In an exemplary embodiment a rotary anode motor is likewise supplied by the inverter circuit which is in the form of a full bridge with two pairs of alternately closable electronic switches. In one bridge diagonal the load (e.g. the x-ray tube) is disposed, while a d.c. voltage source is connected to the other bridge diagonal. The rotary anode motor is capable of connection, via a switch, to a connection point at one side of the load diagonal, and the bridge-half at the opposite side of the load diagonal is capable of being maintained in an open circuit condition during motor operation.

Abstract: The output voltage of the inverter is supplied to a high voltage transformer to which an X-ray tube with a rotating anode is connected. The rotating anode motor is likewise fed by the inverter. To this end, the inverter can be selectively operated with a high frequency for feeding the X-ray tube and a low frequency for feeding the rotating anode motor. But it is also possible to supply the inverter output voltage in parallel to the high voltage transformer and to a frequency divider at whose output the rotating anode motor lies.

Abstract: In an exemplary embodiment, a control loop for the x-ray tube current is present which adjusts the x-ray tube current to a value which is a function of the exposure time and the selected mAs-product. In order that deviations of the x-ray tube voltage from a desired value can be controlled via the x-ray tube current, but that the mean value of the x-ray tube current can nevertheless be kept constant, a phase angle control device, arranged in the primary circuit of the high voltage transformer, can be present as the regulating unit for the mean value of the x-ray tube current. As controller for the x-ray tube voltage, a circuit for the adjustment of the filament current of the x-ray tube can be provided.

A device for effecting a relative movement between the housing and the cathode coils is present, by means of which one of the cathode coils is selectively capable of being covered. The cathode coils can be mounted on a holder which is pivotal about the x-ray tube longitudinal axis by means of electromagnets. The electromagnets can be connected to the output of the filament supply transformer, associated with the respective cathode coil, and a multiplex circuit can be provided for the transmission of the control signals.

Abstract: In an exemplary embodiment, an inverter manifests a load output which is capable of being alternately connected, via a switching apparatus with the poles of a d.c. voltage source. Changeover switches are present by means of which the load output can be selectively connected between a midpoint conductor of the d.c. voltage source and the midpoint of a half-bridge formed by the switching apparatus, or into the diagonal of a full-bridge formed by the switching apparatus. The changeover switches for the formation of the half-bridge, parallel-connect two branches of the full-bridge in each instance. By this means, the inverter is capable of being adapted selectively to a high voltage or a high current load.
