重复频率低阻抗紧凑Marx脉冲功率源
Compact repetitive Marx generator with low impedance
摘要
Abstract
A series of compact repetitive pulsed power systems on the basis of fast Marx generator were developed in Institu-te of Fluid Physics,China Academy of Engineering Physics.They are mainly composed of a fast Marx generator and a repetitive high voltage charging device.There are polypropylene film capacitors with plastic shell,miniaturized gas switches,isolated induc-tors and SF6 gas insulation in these fast Marx generators.An 8-stage Marx generator was designed and tested.It can output re-petitively 5 pulses with peak power of beyond 10 GW,rising-time of 50 ns,pulse width of 150 ns at frequency of 10 Hz.An 18-stage Marx generator has the same structure as the 8-stage Marx generator.It can generate a single pulse with peak power of more than 33 GW and pulse duration of about 160 ns on a resistor load of 18Ω.Its peak power density is up to 150 GW/m3 .But its output pulse has an obvious reverse pulse in the falling time,which is not helpful to drive a diode load.So,a 16-stage coaxial Marx generator was designed,there are four capacitors in parallel in one stage.The coaxial Marx generator has a low inductance and a low output impedance.It can generate a pulse with peak power of 28 GW and pulse duration of 130 ns without reverse pulse on an 12 Ωload.This work is useful for the development of high power compact pulsed power.There are also some work to do in order to enhance the working life and repetitive operation stability of high power compact Marx generator.关键词
