Abstract

L'invention concerne un circuit électronique destiné à faire passer des impulsions de courant fort à travers une charge. Ledit circuit comprend un premier transistor, un circuit destiné à connecter la charge entre le collecteur d'un transistor et une première source de courant continu et un transformateur ayant un enroulement primaire et deux enroulements secondaires dont le premier est connecté à la base du premier transistor et le second soit à l'émetteur soit au collecteur, de façon que les tensions aux bornes des deux enroulements secondaires coopèrent pour commander la génération des impulsions de courant du collecteur du premier transistor. Application à un illuminateur à laser.The invention relates to an electronic circuit for passing pulses of strong current through a load. Said circuit comprises a first transistor, a circuit for connecting the load between the collector of a transistor and a first direct current source and a transformer having a primary winding and two secondary windings, the first of which is connected to the base of the first transistor and the second either at the emitter or at the collector, so that the voltages across the two secondary windings cooperate to control the generation of the current pulses from the collector of the first transistor. Application to a laser illuminator.
