Closing performances of double‐gap laser‐triggered vacuum switch

Abstract: To develop high-voltage-pulsed power switches with better performances, a multi-gap laser-triggered vacuum switch is proposed in this study. Based on established test prototype for double-gap laser-triggered vacuum switch, closing processes of double-gap laser-triggered vacuum switch are discussed combined with laser-produced plasma. Closing performances of double-gap laser-triggered vacuum switch under different gap polarity configurations, operating voltages, laser energies and laser split ratios are investi… Show more

“…The external circuit is composed of multiple pulse-forming network modules based on capacitor banks in parallel. The two rails and armature are connected to the pulse-forming network modules through cables as loads, and pulse power supply [26,27] provides current input to loads according to the specified time sequence. Lorentz force obtained by solving the transient EM field with the external circuit as the source is the direct input to the structural field.…”

“…Reducing the size of the switching components facilitates the opening to improve the compactness of the switching elements. Stereo stacking is an effective method used extensively in MARX, linear transformer driver circuits [23][24][25][26]. The maximum potential difference between the series circuit boards is 24 kV, the breakdown distance of air is 0.8 cm, and its distance is set to 1.5 cm.…”

“…Compared with arc discharges, active species can produce more energy efficiently through the rich non-equilibrium chemical processes in spark plasma. The unique features of spark discharge plasma have attracted increasing attention from the community of ignition and combustion [2][3][4][5], flow control [6,7], surface treatment [8][9][10], energy conversion [11][12][13], high-voltage switch design [14,15], laser ignition [16,17], and material engineering [18,19].…”
