FIELD: electrical engineering. ^ SUBSTANCE: present invention can be used for measuring anode current and voltage across the anode of an X-ray tube. The device for measuring anode current and voltage across the anode of an X-ray tube has an X-ray tube with a grounded cathode, a high voltage source, the pole terminal of which is connected to the anode the X-ray tube, an anode current sensor, the input of which is connected to the minus terminal of the high voltage source, and a voltage divider, connected in parallel to the high voltage source. The anode current sensor is made in form of a current-to-voltage converter on an operational amplifier with a resistor in a negative feedback circuit, the input of which is connected to the minus terminal of the high voltage source. ^ EFFECT: simple circuit for measuring and stabilising anode current of an X-ray tube, as well as a wider range of stabilised operational anode currents of an X-ray tube. ^ 2 dwg |
