The device comprises a switching power supply (1) provided with an electronic switching member (T₁), the closure of which controls the supply of an inductor (L₁) which discharges, on reopening of the member, in a capacity (C₁) at the terminals of which the output voltage of the device appears, characterized in that it comprises (a) memory means for recording a series of image numbers of successive segments of the predetermined waveform, (b) a clocked digital counter (2), and (c) means (3) for successively loading this counter (2) with each of the numbers in the sequence as a counting terminal operated by the counter (2), the latter controlling cyclically closing the switching member (T₁) during a predetermined time interval, each time the counting achieved reaches the terminal thus fixed. |
