Abstract
A generator is described for X-ray diagnostics, with a high-voltage transformer with a primary coil connected or with the grid and a secondary coil feeding the X-ray tube and with a rectifier bridge situated in the primary circuit of the high-voltage transformer. The direct current branch of the rectifier bridge contains a filter capacitor and a thyristor which is opened and closed by means of a pulse duty factor determining the capacitor voltage and thus the voltage of the X-ray tube. An LC-tuned circuit is connected to the thyristor whose capacity is discharged to the conductive thyristor so that the thyristor is quenched via a free-wheel diode arranged in parallel to the thyristor. In this way, a high switching frequency of the thyristor and, consequently, a low ripple of the X-ray tube voltage is obtained.
