| 摘 要： | 基于10级模块串联的1 MV快脉冲直线型变压器驱动源装置,分别开展了1～3个模块在不充电或不触发时装置的整体输出参数测试。结果表明,在二极管负载阻抗基本不变的情况下,装置输出电流和电压降低的数值约为故障模块数与总模块数的比值。与所有模块正常工作时相比,脉冲上升时间分别增加10,22和32 ns,脉冲宽度分别增加13,23和48 ns。根据电路分析以及模块实际电参数建立了装置的等效电路模型,模拟得到的不同数量模块不工作时的输出电压变化趋势与实验结果基本一致,并利用电路模型对故障模块中开关两端的电压进行了模拟和分析。

| Abstract: | The performance of the 10-stage LTD generator is investigated in experiments with some stages uncharged or untriggered. The result shows that both the current and the voltage decrease by almost 10%, 20% and 30%, the pulse rise-time increases by 10, 22 and 32 ns and the pulse width increases by 13, 23 and 48 ns, for 1, 2 and 3 malfunctioning stages respectively. Compared with the LTD generator in good condition, the equivalent circuit simulation of the LTD generator working abnormally demonstrates that the variation trends of the current and the voltage in the load agree well with the experimental results. In addition, the induced voltage on the switch in the malfunction stage is simulated and analyzed. |
