1. A direct voltage converter system (1, 1'"'"'), comprising:

  • an input (In) for feeding an input voltage (U _ In); and

    a step-up regulator section (2) for stepping up the input voltage (U _ in) in a regulated manner to a regulated first output voltage (U _ Out

         1) and for providing the first output voltage (U _ Out

         1) at a first supply output (Out

         1), wherein the step-up regulator section furthermore has a series circuit of a first inductance (L1) and a first diode (D1), the first inductance (L1) and the first diode (D1) being electrically connected to one another at a first connection point (P1), wherein the first diode (D1) is arranged with a conduction direction;

    the first diode (D1) is conducted in the direction from the first connection point (P1) to the first supply output (Out

         1); and

    the step-up regulator part furthermore has a regulating device (S1) and a switching device (T1) controllable by the regulating device (S1) for opening or closing an electrical connection in a controlled manner between a first contact point (K1) of the switching device and a second contact point (K2) of the switching device (T1), wherein the first contact point (K1) of the switching device is electrically connected to the first connection point (P1) and the second contact point (K2) of the switching device is electrically connected to ground either directly or via a first resistor (R1);

    it is characterized in that the preparation method is characterized in that,the direct voltage converter system (1, 1'"'"') furthermore has a voltage conversion section (3) for converting the input voltage (U _ in) into a second output voltage (U _ Out

         2) in a manner controlled by the regulating device (S1) and for providing the second output voltage (U _ Out

         2) at a second supply output (Out

         2), wherein the voltage conversion section (3) has a series circuit of a second inductance (L2) and a second diode (D2), the second inductance (L2) and the second diode (D2) being electrically connected to one another at a second connection point (P2), wherein the second diode (D2) is arranged with the following conduction direction;

    the second diode (D2) is conducted from the second connection point (P2) to the second supply output (Out

         2); and

    the voltage conversion part (3) has a coupling capacitor (C3) electrically coupling the first connection point (P1) and the second connection point (P2),wherein the first output voltage (U _ out

         1) is directed back to the regulating means (S1) to regulate the boost based on the first output voltage (U _ out

         1).
