Abstract: front page image
(EN)A control system for controlling an output regulator having a regulated output. The control system including an output sensor to generate a digital sense signal to indicate within which of at least three reference ranges the regulated output is included. Each of the at least three reference ranges including a plurality of possible values of the regulated output. A digital controller, responsive to the digital sense signal, to generate a drive signal to control the regulated output, the digital controller including and selecting between at least three operating modes, a selected one of the operating modes to generate the drive signal. The digital controller further generates a duty cycle estimation for controlling the power stage. The digital controller further comprises a delay line to adjust the duty cycle estimation.
(FR)La présente invention concerne un système de commande servant à commander un régulateur de sortie à sortie régulée. Le système de commande comporte une sonde de sortie servant à produire un signal numérique de sonde servant à indiquer dans laquelle d'au moins trois plages de référence se trouve la sortie régulée. Chacune de ces trois plages de sortie comporte une pluralité de valeurs possibles de la sortie régulée. Le système de commande comporte également un module de commande numérique qui, en réaction au signal numérique de sonde, produit un signal de commande servant à commander la sortie régulée.
