摘要

我们制作了一种新型的8 kV光触发功率晶闸管，具有集成过压自保护功能。特殊的凹槽结构提高了光敏度。四个放大门级与集成限流电阻一起保证了安全和均匀的导通行为。动态和静态功率损耗的改善可以通过局部寿命的减少和阻塞型pn结的穿透深度的减少来实现。

A novel 8 KV light-triggered thyristor with overvoltage self protection

We have fabricated a novel 8 kV light-triggered power thyristor with integrated overvoltage self-protection. The light-sensitivity was improved by a special groove structure. Four amplifying gate-stages together with an integrated currentlimiting resistor guarantee a safe and homogeneous turn-on behavior. An improvement of the dynamic and static power losses could be obtained by a local lifetime reduction and by a decrease of the penetration depths of the blocking pn-junctions.
