METHOD OF DRIVING AN ELECTRICAL LOAD, AND CORRESPONDING SIGNAL GENERATOR AND CIRCUIT

A method for driving a unidirectional current through an electrical load, such as one or more LED modules, by applying thereto a PWM-modulated signal that swings between a high value and a low value envisages choosing said high value and said low value as nonzero values having a same sign.
