Title (EN) CONTROLLING TRANSITIONS IN OPTICALLY SWITCHABLE DEVICES
(FR) COMMANDE DE TRANSITIONS DANS DES DISPOSITIFS OPTIQUEMENT COMMUTABLES
Abstract:
(EN) Aspects of this disclosure concern controllers and control methods for applying a drive voltage to bus bars of optically switchable devices such as electrochromic devices. Such devices are often provided on windows such as architectural glass. In certain embodiments, the applied drive voltage is controlled in a manner that efficiently drives an optical transition over the entire surface of the electrochromic device. The drive voltage is controlled to account for differences in effective voltage experienced in regions between the bus bars and regions proximate the bus bars. Regions near the bus bars experience the highest effective voltage. In some cases, feedback may be used to monitor an optical transition. In these or other cases, a group of optically switchable devices may transition together over a particular duration to achieve approximately uniform tint states over time during the transition.
(FR) La présente invention concerne, selon des aspects, des organes de commande et des procédés de commande permettant d'appliquer une tension de commande à des barres omnibus de dispositifs optiquement commutables tels que des dispositifs électrochromiques. De tels dispositifs sont souvent situés sur des fenêtres telles que du verre architectural. Dans certains modes de réalisation, la tension de commande appliquée est commandée d'une manière qui commande efficacement une transition optique sur toute la surface du dispositif électrochromique. La tension de commande est commandée pour tenir compte de différences de la tension efficace appliquée dans des régions entre les barres omnibus et des régions à proximité des barres omnibus. Les régions à proximité des barres omnibus sont soumises à la tension efficace la plus élevée. Dans certains cas, des informations en retour peuvent être utilisées pour surveiller une transition optique. Dans ces cas ou dans d’autres cas, une pluralité de dispositifs optiquement commutables peuvent transiter conjointement pendant une durée particulière pour obtenir des états de teinte approximativement uniforme pendant le temps de la transition.
