The invention concerns a device for supplying direct current to a load (R) capable of being connected to output terminals (AK). Said device comprises: a semiconductor switch element (T) for applying, in rhythmic mode, a supply voltage (V) to a primary winding (L1) of a transformer on the basis of a series of starting pulses applied to a control input (G) of the semiconductor switch element (T); a starting circuit (AS) for producing the starting pulses (AI), comprising a first input terminal (ASE1) for applying a regulating signal (RS) depending on the load, analogous thereto, generated by a measuring device (MA) signal on which depends the duration of the individual starting pulses (AI), and a second input terminal (ASE2) for applying a starting signal (SS) defining the time for triggering the starting signals (AI); and a pulse generator (IG) comprising an output terminal (IGA) connected to the starting circuit (AS) input terminal (EK2), for making the starting signal (SS) available in the form of pulses, according to the regulating signal (RS) which is also directed to a first input terminal (IGE1) of the pulse generator (IG), the regulating signal (RS) capable of acting on the time variation between the starting signal (SS) individual pulses. |
