Abstract
Disclosed is a device to obtain a DC voltage V.sub.p that is adjustable in a wide range of values. To a rectifying and filtering circuit, there are applied AC pulses. The quantity of electricity of these AC pulses is constant for each pulse, and their frequency F varies as a function of the voltage V.sub.p to be obtained. To this effect, a DC/AC converter of the hyporesonant type is used. The device can be used for providing bias for a focusing element of an X-ray tube.
