摘要
介绍了一种基于传输线变压器(TLT)的多开关脉冲功率技术。该技术可以像Marx发生器一样实现多个开关的自动同步,而且在输出上更具灵活性:不仅可以通过电压叠加获得高电压输出,而且可以通过电流叠加实现大电流输出,或者用于同时驱动多个独立的负载。基于该技术已成功开发了10火花开关的短脉冲系统。理论设计了带有20开关和20级TLT的脉冲发生器,单脉冲能量140J,预计峰值功率可达5GW,可实现多种不同输出方式以满足不同应用需求。
The paper introduces a multiple-switch pulsed power technique based on transmission-line-transformer（TLT）.In the circuit,all the switches can synchronize themselves automatically like in a Marx generator.At the output side,a variety of output options are possible,i.e.high voltage,large current or independent pulse generation.A 10-switch,10-stage TLT system has been successfully developed.At the moment,a repetitive large power generator with 20 switches and a 20-stage TLT is being developed.The peak power is estimated to be 5 GW with a total energy of 140 J per shot.Up to 100 independent simultaneous outputs can be realized with the same peak power.
