A driver circuit (54) is provided for a stepper motor (52) which utilizes a processor (62) that outputs a PWM signal. The driver circuit (54) includes an H-bridge circuit having first and second inputs (64,90), and a switching circuit (68) having an input (66) and an output (88). The first H-bridge input (64) and the switching input (66) connect to the PWM signal output from the processor (62), and the switching output (88) connects to the second H-bridge input (90). The switching circuit (68) performs an inversion of a duty cycle of the PWM signal when the PWM signal is present, and a non-inversion of the duty cycle when the PWM signal is not present.

Selon l'invention, un circuit de commande (54) est utilisé dans un moteur pas-à-pas (52) qui se sert d'un processeur (62) qui produit un signal PWM (à modulation d'impulsions en durée). Le circuit de commande (54) comprend un circuit de pont en H comprenant une première et une seconde entrée (64,90), et un circuit de commutation (68) comprenant une entrée (66) et une sortie (88). La première entrée (64) du circuit de pont en H et l'entrée (66) du circuit de commutation sont connectées à la sortie de signal PWM du processeur (62), et la sortie (88) du circuit de commutation est connectée à la seconde entrée (90) du circuit de pont en H. le circuit de commutation (68) réalise une inversion d'un facteur d'utilisation du signal PWM lorsque le signal PWM est présent, et une non-inversion du facteur d'utilisation lorsque le signal PWM n'est pas présent.
