    Abstract: A current source (Figs. 1A and 1B) for establishing a relatively constant current through widely differing impedances (12, 12A) comprising a voltage potential regulator (20-41) for adjustably regulating a supplied potential to provide a current to a current controller (42, 43, 45-56) with a current sensor (44) to supply a signal to the current controller from the signal controller (42, 43, 45-56) to control the voltage potential regulator (20-41). A further current rise time regulator (62-74) is provided to increase the rise time occurence provided to a commutated load (12, 12a).

    Abstract: Une source de courant (figures 1A et 1B) permettant d'établir un courant relativement constant à des impédances (12, 12A) très différentes, comprend un régulateur de tension (20-41) destiné à réguler de manière variable un potentiel fourni afin de délivrer un courant à une unité de régulation de courant (42, 43, 45-56) au moyen d'un capteur de courant (44), afin de transmettre à ladite unité de régulation de courant un signal provenant de l'unité de régulation de signaux (42, 43, 45-56) de manière à commander ledit régulateur de tension (20-41). On a prévu un autre régulateur (62-74) de temps de montée de courant afin d'augmenter le temps de montée accordé à une charge commutée (12, 12A).
