A Multiple-switch Technology for High-power Pulse Discharging

摘要：

This article presents our recent research on a new multiple-switch pulsed power technology. With this technique, multiple spark-gap switches can be synchronized automatically, like in Marx generator. However, in contrast to a Marx, Pulsed power can be produced either at a high voltage or with a large current, or it can be used to drive multiple independent loads simultaneously. It is promising for the development of an efficient large pulsed power supply with an increased lifetime. Through use of this technique,an efficient ten-switch prototype system has been successfully developed. Experimental results show that 10 spark-gap switches can be synchronized within about 10 ns. The system has been successfully demonstrated at repetition rates up to 300 pps (Pulses Per Second). Pulses with a rise-time of about 11 ns, a pulse width of about 55 ns, an energy of 9 J-24 J per pulse, a peak power of 300 MW-810 MW, a peak voltage of 40-77 kV, and a peak current of 6 kA-11 kA have been achieved with an energy conversion efficiency of 93％-98％.
