摘要: 讨论了一种低阻抗、高储能密度、可输出中等高压的百ns脉冲形成技术，其输出波形质量较好；采用磁感应电压叠加技术将该脉冲形成装置输出的中等高压脉冲叠加到应用需求的高电压高功率脉冲。研究表明单个感应模块可在2.8 Ω的负载上获得脉冲宽度为220 ns，前沿为50 ns的中等高压脉冲。Abstract: Increasing importance is being placed on the compact and lightweight repetitive high power nanosecond pulse generator. Based on the ceramic capacitor with neglectable self-inductance, a new high energy density pulse forming module which can form low impedance pulse easily has been developed. The mid-high voltage pulses provide by the modules are used tp produce the demanding high voltage by inductive voltage adding. The experimental results indicate that the rise time of the mid-high voltage pulse generated by single linear transformer driver(LTD) cell is about 50 ns and the pulse width is about 220 ns when the matching load is 2.8 Ω．
