Abstract

L'invention concerne un système de compensation conçu pour être utilisé avec un dispositif électronique portable piloté par PWM et alimenté par batterie, permettant de fournir une alimentation régulière à la charge du dispositif malgré la chute de tension de la batterie résultant de l'épuisement de celle-ci, comprenant : un circuit diviseur de tension servant à régler la tension proportionnellement sur une plage mesurable ; un convertisseur analogique/numérique recevant la sortie du diviseur de tension et la convertissant en une valeur de tension numérique ; et une unité de microtraitement servant à exécuter des étapes de code logiciel pour recevoir une entrée de tension numérique et une entrée de réglage de puissance déterminée par l'utilisateur afin de déterminer un rapport cyclique de compensation à faire appliquer à la PWM par le logiciel pour alimenter la charge de manière régulière au niveau de puissance déterminé par l'utilisateur, malgré la diminution de la tension de la batterie résultant de l'épuisement de celle-ci.
