Abstract: A control circuit for a voltage source generates a reference signal for a voltage source, wherein the reference signal indicates a requested output voltage to be generated by the voltage source. A digital feed-forward control circuit computes a digital feed-forward regulation value indicative of a requested output voltage by determining a maximum voltage drop at strings of solid-state light sources. A digital feed-back control circuit determines a minimum voltage drop for current regulators/limiters for the strings and determines a digital feed-back correction value as a function of the minimum voltage drop. The control circuit then sets the reference signal after a start-up as a function of the digital feed-forward regulation value and corrects the reference signal as a function of the digital feed-back correction value.
