介绍了输出电流幅值为1 MA,电流上升时间为100 ns的快脉冲直线型变压器驱动源(LTD)模块的设计.模块由48个子块并联组成,每个子块由2个电容器和一个多级气体开关串联组成.48个开关由8路高压脉冲触发,每路高压脉冲(100 kV/50 ns)触发6个开关.电路模拟显示,在充电 90 kV条件下,输出电流幅值为1.04 MA,电流上升时间为84.5 ns(0～100%)和52 ns(10%～90%).电路模拟时的参数设置以实验数据为基础,开关的工作条件与已研制成功的100 kA-LTD模块中的开关工作条件近似,模块设计工作于腔体注油状态以保证高压运行安全,能够保证模块达到设计要求.

The design of a 1 MA linear transformer driver(LTD) stage is introduced, whose current risetime is 100 ns. The stage consists of 48 parallel bricks, each of which consists of two capacitors (40 nF/100 kV) and a multi-gap gas switch in series. The 48 switches are triggered by 8 high voltage pulses (100 kV/50 ns) with each pulse triggering 6 switches. According to the simulation results, when charged to 90 kV, the output current of this stage is 1.04 MA, and the current risetime is 84.5 ns (0～100%) and 52 ns (10%～90%). Simulation is based on experimental data. Work conditions of the switches are similar to those in 100 kA-LTD stage which has been tested successfully before. The 1 MA-LTD stage will be filled with transformer oil to ensure safty when charged to high voltage.
