Abstract
An electrical power supply for an X-ray tube has a source capable of providing constant current at a desired potential to a capacitor means which supplies pulses of current in excess of the source current to the X-ray tube. As each pulse is supplied, the potential at the output of the supply tends to drop. One side of the capacitor means is connected to the output. A compensator is connected to the other side of the capacitor means and responds to a drop in the output potential to apply to the other side of the capacitor means a voltage which maintains the output voltage constant.
