(EN) STAGGERED DRIVING ELECTRICAL CONTROL OF A PLURALITY OF ELECTRICALLY CONTROLLABLE PRIVACY GLAZING STRUCTURES
(FR) COMMANDE ÉLECTRIQUE DE PILOTAGE ÉCHELONNÉ D'UNE PLURALITÉ DE STRUCTURES DE VITRAGE DE CONFIDENTIALITÉ POUVANT ÊTRE COMMANDÉES ÉLECTRIQUEMENT
Abstract
(EN)
An electrical driver can be used to provide electrical drive signals to a first and second electrically controllable optical privacy glazing structures. A first electrical drive signal can be applied to the first privacy glazing structure and a second electrical drive signal can be applied to the second privacy glazing structure. Applying the first and second electrical drive signal can comprise temporally staggering delivery of the first and second electrical drive signals such that a peak power draw and/or a peak current draw from the first privacy glazing structure is temporally offset from a peak power draw and/or a peak current draw from the second privacy glazing structure. Staggering can include delaying the application of one electrical drive signal relative to the other, phase shifting one electrical drive signal relative to the other, or a combination thereof.

L'invention concerne un circuit de pilotage électrique qui peut être utilisé pour fournir des signaux de pilotage électriques à des première et deuxième structures de vitrage de confidentialité optique pouvant être commandées électriquement. Un premier signal de pilotage électrique peut être appliqué à la première structure de vitrage de confidentialité et un deuxième signal de pilotage électrique peut être appliqué à la deuxième structure de vitrage de confidentialité. L'application du premier et du deuxième signal de pilotage électrique peut comprendre l'échelonnement dans le temps de la distribution des premier et deuxième signaux de pilotage électrique de sorte qu'un appel de puissance de crête et/ou un appel de courant de crête provenant de la première structure de vitrage de confidentialité sont décalés dans le temps par rapport à un appel de puissance de crête et/ou un appel de courant de crête provenant de la deuxième structure de vitrage de confidentialité. L'échelonnement peut comprendre le retardement de l'application d'un signal de pilotage électrique par rapport à l'autre, le déphasage d'un signal de pilotage électrique par rapport à l'autre, ou une combinaison de ceux-ci.
