    • A system for supplying a selected voltage between the anode and cathode of an x-ray tube independent of power source voltage variations couples the x-ray tube power supply to the source with a transformer whose output voltages are selectable with tap switches. Prevailing source voltage and selected applied voltage are sensed and represented by analog signals which are converted to binary digital codes that form addresses for a read-only memory. The read-only memory is programmed with data representative of the pattern in which the tap switches should be set for the transformer to supply the selected voltage at the prevailing source voltage. When addressed by combinations of code words representative of the selected and source voltages, the memory outputs a code word that is used to set the switches in the corresponding pattern.
