Abstract

PURPOSE:To reduce the loss of a thyristor provided in a circuit for turning a gate turn-off thyristor (GTO) through the constitution of parallel connected thyristors. CONSTITUTION:When a GTO1 turns off, a transistor 7 turns on and thyristors 81 and 82 turn on. Thus, an inverse current flows between the cathode and gate of the GTO1 and the GTO1 turns off. Since the thyristors 81 and 82 are parallel connection of small capacity of thyristors, the loss of the thyristors 81 and 82 caused when an off-gate current flows to the GTO1 can be decreased.
