【Abstract】 This paper presents a 350 kV nanosecond pulse voltage generator (NPVG). The voltage pulsed width can be adjusted from 30 to 160 ns. The generator consists of Marx generator, pulsed forming line (PFL), main switch and matched impedance. The output voltage of Marx generator is higher than nU c(n-the stage number of Marx generator, U c-the charging voltage of capacitor). When the pulse forming line is terminated with impedance that is higher than the characteristic impedance of PFL, the voltage pulse on the load is higher.更多还原
