Abstract

A high-power generator based on small TB133-250-24 thyristors, which contains four thyristor modules with an operating voltage of 24 kV, is considered. The parameters of control pulses and protective circuits that provide low switching energy losses in series-connected thyristors and the absence of dangerous overvoltages upon their enabling are determined. The results of generator testing at a frequency of 10 Hz are presented. It is able to switch microsecond current pulses with an amplitude of 12 kA and a front of 0.8 μs. The possibility of scaling these results is shown.

摘要

考虑一种基于小型TB133-250-24晶闸管的大功率发电机，其中包含四个工作电压为24 kV的晶闸管模块。确定控制脉冲和保护电路的参数，这些参数可在串联晶闸管中提供较低的开关能量损耗，并且在使能时不存在危险的过电压。给出了发电机在10 Hz频率下的测试结果。它能够切换幅度为12 kA，前沿为0.8μs的微秒电流脉冲。显示了缩放这些结果的可能性。
