The invention relates to the DC voltage generators of the resonance converter type operating in continuous or discontinuous mode according to the hyporesonant mode. The invention lies in a digital calculation circuit (42) which makes it possible, in the course of each half-cycle of the converter (41), to calculate the instant of triggering of the semiconductor of the converter (41) for the following half-cycle so as to obtain, on the one hand, as short as possible a time for establishing the high voltage (V) and, on the other hand, to achieve minimum low-frequency residual ripple. The invention applies to voltage generators used to supply X-ray tubes. <IMAGE>
