Abstract
Abstract A direct-current high voltage obtained by rippling, stepping-up and rectification of a direct-current low voltage is regulated in such a manner as to ensure that the maximum value of direct-current high voltage attains a predetermined peak value at each ripple pulse of the inverter. To this end, a following pulse of the inverter is produced as soon as the high voltage of the direct-current high-voltage signal has become lower than the predetermined peak value reduced by the measurement of a variation in said direct-current high voltage during a preceding pulse.

A method for regulating the voltage of a voltage signal, comprising the steps of: producing a ripple in a direct-current low voltage signal by means of a resonance invertor having an adjustable pulse frequency to thereby provide a low ripple-voltage signal; stepping up said low ripple-voltage signal in order to produce a high ripple-voltage signal; rectifying and filtering a voltage of said high ripple-voltage signal in order to produce a direct-current high voltage signal; regulating a voltage of said direct-current high voltage signal; measuring a variation of said voltage of said direct-current high voltage source during a ripple pulse of said invertor; and gating the starting time of said invertor for a following ripple pulse wherein said gating occurs as soon as the high voltage of the direct-current high-voltage signal has become lower than a predetermined peak value minus said measurement of variation of said direct-current high-voltage during a preceding time, to thereby insure that the maximum value of said direct-current high-voltage signal reaches a predetermined maximum value at each ripple pulse; validating the operation of said invertor at each pulse in order to avoid production of a following pulse prior to the end of a preceding pulse.
