Abstract

Régulateur pour moteur électrique comprenant un circuit oscillateur à tension de commande (10), dont la sortie est transformée en forme l'onde triangulaire par un générateur de forme d'onde (12). La sortie du générateur est appliquée à une entrée d'un comparateur (14). L'autre entrée est alimentée par un signal d'erreur (e) indiquant la différence entre la sortie demandée et la sortie réelle. Pour atténuer le bruit acoustique du régulateur, la période et l'amplitude de la sortie de l'oscillateur et, par conséquent, du générateur se forme d'onde, sont modifiées par un générateur à séquence pseudoaléatoire (18) qui est connecté à l'oscillateur. La sortie du comparateur est une onde rectangulaire de rapport marque/espace variable.
