摘要

栅极关断晶闸管(GTO)门控电路，尤其是关断电路，是GTO设备可靠运行的关键。本文介绍了一种用于600A级大功率GTO的新型门控电路。该旁路电路可提供200A的负脉冲，其上升速率为30A/us。它的功耗降低到以前型号的20%。此外，还介绍了导通电路和负偏置电路。

Gating circuit developed for high power thyristors

Gate turn off thyristor (GTO) gating circuits, especially off-gating circuits, are the most important for reliable operation of GTO equipment. This paper describes a new gating circuit for high power GTO of 600A class. The off-gating circuit can provide a negative pulse of 200A with its rate of rise of 30A/us. Its power dissipation decreases to 20 percent of a previous type. The on-gating and negative bias circuits are also described.
