Abstract:
An embodiment of method is described for controlling a voltage regulator of the type comprising at least one modulator of the PWM type, the method comprising: 1) generation of a control voltage signal for said PWM modulator; 2) frequency modulation of said control voltage signal obtaining a modulated control voltage signal having an harmonic at a switching frequency of said voltage regulator of reduced entity with respect to said control voltage signal; and 3) application of said modulated control voltage signal to said PWM modulator for generating a driving signal for said voltage regulator.
