Characteristics of a Multi-channel Surface Discharge Switch for a High Current Generator

An experimental study was carried out of the effect produced by charging voltage and load inductance on the characteristics of a multi-channel surface discharge switch. Impedance, active resistance and inductance were measured at the different regimes of the switch operation. A quasistationary discharge stage was detected to occur at time t = 5...18 mus at constant inductance and active resistance of the switch (capacitance C₀ = 79 muF, charging voltage U₀ = 20...25 kV, circuit inductance L_c = 20...100 nH).
