<p>A servosystem for controlling the voltage in X-ray generators includes a system for controlling the voltage of the primary of a high voltage transformer for feeding the X-ray tubes. A servosystem controls the position and adjustment of acceleration, uniform movement and braking, and supplies a direct current motor, of the permanent magnet type and of standard manufacture, which moves the brushes of a three-phase or mono-phase toroidal autotransformer, the operation of which fixes the primary voltage of the high voltage transformer which, in turn, supplies a voltage to an X-ray tube.</p> |
