Abstract

A PWM signal generator to provide a supply current to an electrical load generates PWM signals at a first frequency, the PWM signals having a duty cycle. Operating the generator involves receiving a set point signal indicative of a target average value for the supply current, sensing a sensing signal indicative of a current actual value of the supply current, performing a closed-loop control of the supply current targeting the target value for the supply current via a controller such as a PID Controller which controls the duty cycle of the PWM signals generated by the PWM signal generator as a function of the offset of the sensing signal with respect to the set point signal.
