A conceptional design of synchronized trigger system for fast linear transformer driver is introduced, which is based on single transmission line pulse forming technology. The trigger system consists of Marx generators, pulse forming lines, main switches, transmission lines and output cables. With the equivalent circuit model, the relationship between Marx generator and pulse forming line is studied. As multiple pulse forming lines are driven in parallel, the number of trigger pulses and the efficiency of energy increase, but the amplitude of trigger pulses decreases. The impedance and number of output cables affect the amplitude as well. With increasing the serial number of cable, the amplitude decreases gradually. As the impedance of transmission line increases, the attenuation rate of the amplitude increases consequently. The trigger signals can be also led out at the same time. When single pulse forming line is driven, 60 trigger signals can be obtained with the amplitude of 293 kV and rise time of 11 ns. When five pulse forming lines are driven in parallel, the amount of trigger signals can reach 300, the amplitude of the pulses is 151 kV and the rise time is 11 ns.%提出了一种基于单传输线脉冲成形技术的模块化快脉冲直线型变压器驱动源的同步触发系统的概念设计,主要由级数较少的Marx发生器、脉冲形成线、主开关、脉冲传输线及触发引出电缆等组成.利用等效电路模型,研究了Marx发生器与脉冲形成线的配合关系,当发生器同时驱动多路形成线时,可以有效增加触发脉冲的数量,并能提高能量利用效率,但触发脉冲的幅值会降低.研究了水介质线阻抗与引出电缆数量对触发脉冲的影响,结果表明:随着电缆序号的增加,触发脉冲的幅值逐渐降低,并且水介质线的阻抗越高,幅值降低的速度越快.触发脉冲也可同时引出,驱动单路形成线输出60路时,触发脉冲的峰值约为293 kV.前沿约11 ns；当驱动5路形成线输出300路时,触发脉冲的峰值约为151 kV.前沿约11 ns.
