Abstract
In an exemplary embodiment, a rectifier bridge is inserted in the primary circuit of the high voltage transformer and has an electronic circuit for adjusting the primary current to adjust the amplitude of the x-ray tube voltage pulse waveform. The comparator of the control loop cooperates with a storage circuit which is connected to a release circuit which releases it by means of a release pulse in a short time interval within a half wave of the x-ray tube voltage waveform for storing an instantaneous value of the error until the next release pulse. The storage circuit drives the electronic voltage adjusting circuit to adjust the pulse amplitude without distorting its waveform.
