Abstract

Abstract

A capacitor-loaded parallel plate transmission line model was introduced and its propagating characteristic was analyzed. The loaded capacitor’s distance was decreased to increase the upper limit of PFN’s cutoff frequency and to decrease the impedance dispersion. With the loss-line model, the reflection coefficient at PFN’s end was analyzed and the method to minimize this coefficient was researched. The magnetic coupling for series PFN was also researched and the influences of PFN’s parameters and their arrangement mode on pulse current were analyzed. Based on the technologies of series PFN and Tesla transformer, a 2 GW long-pulse generator was developed, with 300 kV output voltage, 110 ns pulse width and less than 10 ns rise time．
