Abstract

Un procédé pour la commande des dispositifs électrochromes est décrit. Tout d'abord, un cycle de travail de la PWM est modifié pour une valeur Q prédéfinie en fonction d'un signal détecté par un détecteur pendant que le dispositif électrochrome est commuté pour passer à l'état coloré. La valeur Q représente la charge électrique qui correspond à la transmittance à l'état coloré. Puis la PWM est coupée. De ce fait, le temps de réponse pour la coloration et la transmittance du dispositif électrochrome est maintenu dans un intervalle prédéterminé, sans être affecté par la température ambiante, le temps de réglage et le vieillissement des matériaux utilisés. Ainsi, le dispositif électrochrome est plus pratique à utiliser et a une valeur de praticité plus élevée.A method for controlling electrochromic devices is described. First, a work cycle of the PWM is changed to a predefined Q value based on a signal detected by a detector while the electrochromic device is switched to color. The Q value represents the electrical charge which corresponds to the transmittance in the colored state. Then the PWM is cut off. As a result, the response time for coloration and transmittance of the electrochromic device is maintained within a predetermined range, without being affected by the ambient temperature, setting time and aging of the materials used. Thus, the electrochromic device is more convenient to use and has a higher practicality value.
