A current source gate drive circuit (80) includes tow current loops (72), each of which serves as a current transformer primary. Electrically insulating tubes (76) enclose the current loops (72). Current transformer cores (74), around which are wound a certain number of secondary turns, surround the current loops (72). Thyristor gate driver circuits (70) are electrically coupled to the current transformer cores. Each of the driver circuits (70) receives and rectifies ac current signals for the current loops (70) and forms a current pulse train firing signal. A current pulse shaping circuit (64) is connected to the current loops and uses dual resonant LC circuits to generate the ac current signals.

Un circuit d'excitation de grille (80) de source de courant comprend deux boucles de courant (72), chacune servant d'enroulement primaire du transformateur de courant. Des tubes électro-isolants renferment les boucles de courant (72). Des noyaux (70) de transformateur de courant, autour desquels sont enroulés un certain nombre de spires secondaires, entourent les boucles de courant (72). Les circuits d'excitation (70) de grille de thyristor sont couplés électriquement aux noyaux de transformateurs de courant. Chacun des circuits d'excitation (70) reçoit et rectifie des signaux de courant continu provenant des boucles de courant (70) et génère un signal de déclenchement de train d'impulsions de courant. Un circuit de mise en forme (64) d'impulsions de courant est connecté aux boucles de courant et met en oeuvre des doubles circuits résonants à inductance et à condensateur pour générer les signaux de courant continu.
