摘要
设计并测试了用于环境应用的快速硅晶闸管开关系统。利用极低电感测试电路对三种不同器件结构的硅晶闸管进行了表征，证实了冲穿结构和平阳极结构在快速导通特性方面的优越性。为了实现快速导通操作，他们开发了一种用于重复脉冲功率应用的快速大电流栅极驱动电路。硅晶闸管的下降时间为35 ns，电流上升速率为9.5/spl / rlar2 /10/sup 10/ a /s。为了澄清更高电压操作的技术问题，他们采用了三个硅晶闸管串联堆叠来组装发电机，其重复频率为2 kHz。
Pulsed power generator utilizing fast SI-thyristors for environmental applications
Fast SI-thyristor switching systems were designed and examined for environmental applications. The authors characterized three kinds of SI-thyristor with different device structures by using an extremely low inductance testing circuit, and confirmed the superiority of punch-through and flat-anode structures for fast turn-on characteristics. In order to accomplish fast turn-on operation, they developed a fast and high current gate-driving circuit for repetitive pulsed power applications. The SI-thyristors were successfully operated with a fall time of 35 ns and a current rising rate of 9.5/spl rlarr2/10/sup 10/ A/s. To clarify technical issues for higher voltage operation, they employed three SI-thyristors stacked in series to assemble the generator, which was operated with a repetition rate of 2 kHz.
