1. A digital control system for voltage converters, comprising:

  • an oscillator that issues a pulse;

    a duty cycle generator, wherein the pulse is used to load a numerical value stored in a memory of the system into the duty cycle generator;

    a digital counter that stores and alters a duty cycle;

    a first comparator that determines how the duty cycle must be modified; and

    an algorithm generator producing an algorithm that determines the rate of change of the duty cycle.
