Abstract

Système de circuit pour un équipement d'électro-érosion, dont le rapport d'impulsion, la fréquence d'impulsion et l'intensité des impulsions de travail, dirigées sur la fente d'étincelage, sont réglables et qui comprend un générateur d'impulsions et un circuit de décharge, lequel est équipé de transistors qui dirigent le courant de travail sur la fente d'étincelage au rythme des signaux du générateur d'impulsion et lequel se compose d'un circuit d'allumage et d'un circuit de travail, caractérisé en ce que le circuit situé entre la source de tension et la fente d'étincelage comprend des transistors contrôlés par le générateur d'impulsion dont une partie desquels assure, en tant qu'interrupteurs, la connexion et la déconnexion du circuit d'allumage, alors que l'autre partie contrôle, en tant qu'amplificateurs, l'impulsion du courant dans le circuit de travail.
