Title
(EN) MULTIPHASE VOLTAGE REGULATOR WITH MULTIPLE VOLTAGE SENSING LOCATIONS
(FR) RÉGULATEUR DE TENSION POLYPHASÉ À MULTIPLES EMPLACEMENTS DE DÉTECTION DE TENSION
Abstract
(EN) A voltage regulator dynamically adjusts the voltage distribution on a voltage rail based on multiple feedback measurements. The voltage regulator provides electrical power to a voltage rail at multiple power supply locations along the voltage rail. The voltage regulator obtains voltage measurements from multiple voltage sensing locations on the voltage rail and detects a spatially unequal voltage deviation in the voltage rail. The voltage regulator adjusts the electrical power provided to the voltage rail at each of the power supply locations to compensate for the spatially unequal voltage deviation in the voltage rail.
(FR) Un régulateur de tension ajuste dynamiquement la distribution de tension sur un rail de tension sur la base de multiples mesures de rétroaction. Le régulateur de tension fournit de la puissance électrique à un rail de tension à de multiples emplacements d'alimentation électrique le long du rail de tension. Le régulateur de tension obtient des mesures de tension provenant de multiples emplacements de détection de tension sur le rail de tension et détecte un écart de tension spatialement inégal dans le rail de tension. Le régulateur de tension ajuste la puissance électrique fournie au rail de tension à chacun des emplacements d'alimentation électrique pour compenser l'écart de tension spatialement inégal dans le rail de tension.
