Abstract:
In the elect rothermal chemical and electromagnetic launch technolog y, the hig h-pow er pulsed sour ces o ccupy a very impo rtant place. The sw itch is an important part of the high-power pul sed sour ces. This paper intr oduced the characterist ic and the main co nstr uct io n of the high-power g as sw itches. It int roduced especially design and feature of HG-100 g as sw itch and analy zed it s problems and improv ement s of gas sw itches. Research made it clear that the instant addition in t rigg ering pulse to the electr ic plasma decided the act ion t ime and the stability of the sw itches. T he velocity of high-elect ric co nduct iv ity plasma in the gap decided the gr adient of pulse. The limit frequency of the stable act ion of the pulsed pow er so urce depended on the reinstated time of the gap insulation.
