Influence of trigger voltage on ± 100 kV multi-gap multi-channel switch performance

The mutli-gap mutli-channel spark switch is of low induance and low jitter, thus it has important application in the pulse power technology. This paper presents a ± 100 kV mutli-gap mutli-channel spark switch used for fast linear transformer driver(LTD) . The experiment studies the influence of the switch triggering breakdown characteristic of the switch with different trigger voltage polarity and different trigger voltage, then analyzes different phases delay time and jitter of the gas spark switch under different voltage. Typical results are: the influence of the switch triggering breakdown characteristic of the switch with the trigger voltage polarity is small; the delay time as well as its jitter is decreasing while the trigger voltage is increasing. The paper also analyzes the tr
