摘　　要：介绍了直线型变压器驱动源（LTD）产生快脉冲的基本原理及技术优势，阐述了快脉冲LTD模块设计的要点，设计了输出脉冲上升时间小于100ns的快脉冲LTD模块，并进行了初步的实验研究。实验得到该LTD模块充电士16kV时，短路放电的电流峰值为23．7kA，电流振荡1／4周期为69.6ns；充电±50kV驱动0．850负载时，电流峰值为41．4kA，上升时间为36．8ns（10％-90％）和60．8ns（0-100％）。The principle and technical advantages of a linear transformer driver are introduced and the critical points in designing the fast LTD stage are presented. A fast LTD stage with current rising time less than 100 ns was designed and primary experiments were conducted on this stage. According to the experiment results, the stage can provide a current of 23.7 kA with a quarter period of 69.6 ns to a shorted load when charged to ±16 kV. When charged to ±50 kV, the stage can provide a current of 41.4 kA in 36.8 ns （10%-90% peak value of current） to a matched load of 0. 85 Ω.
