The present invention provides a drive and control apparatus provides a desired switched current to a load including a string of one or more electronic devices. A voltage conversion means, based on an input control signal converts the magnitude of the voltage from the power supply to another magnitude that is desired at the high side of the load. A dimming control means provides control for activation and deactivation of the load and may further provide a means for current limiting. A feedback means is coupled to the voltage conversion means and a current sensing means and provides a control signal to the voltage conversion means that is indicative of voltage drop across the current sensing means which represents the current flowing through the load. Based on the control signal received, the voltage conversion means can subsequently adjust its output voltage such that a constant switched current is provided to the load.
La présente invention se rapporte à un appareil d'entraînement et de commande, qui fournit un courant commuté désiré à une charge comportant une chaîne formée d'un ou plusieurs dispositifs électroniques. Un moyen de conversion de tension convertit, à partir d'un signal de commande d'entrée, l'amplitude de la tension issue de l'unité d'alimentation en une autre amplitude, qui est l'amplitude désirée au niveau du côté haut de la charge. Un moyen de commande de l'intensité lumineuse commande l'activation et la désactivation de la charge, et peut également comprendre un moyen de limitation du courant. Un moyen de contre-réaction, qui est couplé au moyen de conversion de tension et à un moyen de détection du courant, fournit au moyen de conversion de tension un signal de commande indiquant une chute de tension aux bornes du moyen de détection du courant, lequel détermine le courant traversant la charge. A partir du signal de commande reçu, le moyen de conversion de tension peut régler sa tension de sortie de façon à fournir un courant commuté constant à la charge.
