摘要: 设计了基于Blumlein 脉冲形成网络的直线变压器驱动源单元模块。双路阻抗各为20 Ω的Blumlein 脉冲形成网络对称连接于直线变压器驱动源(LTD)的初级绕组上，此种接法降低了脉冲形成网络(PFN)的设计难度，有利于形成更好的脉冲。在LTD次级绕组所接的10 Ω匹配负载上输出高压脉冲，实验结果表明，单个LTD模块输出脉冲半高宽约200 ns，前沿约为55 ns，平顶约为100 ns。Abstract: A cell module of linear transformer driver (LTD), based on Blumlein pulse forming network (PFN), is designed. Two Blumlein PFNs with 20 Ω resistance are symmetrically connected with the LTD’s primary coil. The connection reduces the design difficulty of PFN and improves the output pulse quality. High voltage pulses are derived from a 10 Ω matching load connected with the LTD’s secondary coil. The output pulse of the LTD module is about 200 ns in duration with a rise time of about 55 ns and a flat top of about 100 ns．
