Abstract:
Characteristics of high-current arc discharge in H 2 , N 2 , air and SF 6 have been investigated to develop a high-efficiency, high-repetition pulse power switch. The discharge parameter was typically 5–50 kV, 12–16 kA, with pulse duration around 600 ns. Energy transfer efficiencies and the recovery characteristics of breakdown voltage have been evaluated using a charge transfer circuit. The energy transfer efficiency was found to be much higher for H 2 . The recovery times required to obtain 50% of initial breakdown voltage are evaluated to be 0.5 ms, 2 ms, and 3 ms for H 2 , SF 6 and air, respectively. The arc column was observed to expand with a supersonic velocity which produced a strong shock wave. The volume of hot gas remaining after the discharge was found to be much smaller for H 2 , as compared with SF 6 .
