Abstract
Equipment for the generation of a stabilized high direct voltage is described, and includes: a step-up transformer (2) whose primary is supplied with a direct voltage and which is designed in such a way as to have dispersed inductances and parasitic capacitances which cause a resonance effect on the opening of the primary; a rectifying circuit (3) to rectify the voltage at the terminals of the secondary winding of the step-up transformer (2); a switch (11) which, when in the closed condition, connects the primary winding of the step-up transformer (2) to ground; and circuits (6,7,8,9) for controlling the opening and closing of the switch (11).
