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.
