1. A device for obtaining DC voltage, comprising:

  • a DC voltage source;

    a DC-voltage-to-pulse-voltage converter;

    wherein inputs of the DC-voltage-to-pulse-voltage converter are connected to outputs of the DC voltage source;

    a pulse-voltage-to-DC-voltage converter having an output for connection to a first terminal of a load, and corresponding inputs of which are connected to corresponding outputs of the DC-voltage-to-pulse-voltage converter;

    a regulator, having a first input for connection to a second terminal of the load;

    a proportional regulator, an output of which is connected to a second input of the regulator;

    a DC output voltage selector operably associated with the outputs of the DC-voltage-to-pulse-voltage converter;

    a control circuit, a first input of which is connected to an output of the DC voltage output selector, and an output of which is connected to a control input of the DC-voltage-to-pulse-voltage converter; and

    a feedback circuitry having a first terminal and a second terminal, wherein the first terminal of the feedback circuitry is connected to an input of the proportional regulator and the second terminal of the feedback circuitry is connected to an output of the regulator, wherein a second input of the control circuit is connected to the first input of the regulator that is configured for connection to the second terminal of the load.
