摘要

A high-power high-voltage generator that forms aperiodic current pulses of artificial lightning of a temporal form of 10 mu s/350 mu s and an amplitude of +/-(100-200) kA with tolerances, which are normalized according to the IEC 62305-1-2010 International Standard, is described. The circuit and design solutions are described that make it possible, using a generator that is developed on the basis of capacitive energy storages, to provide the generation of aperiodic positive (negative) current pulses of a simulated lightning across an electric load with an ohmic resistance of 0.1 Omega and an inductance of 1.5 mu H. The time in which the magnitude of the pulse amplitude I (m) reaches 106 kD is t (m) = 24 mu s, the pulse duration at a level of 0.5I (m) is tau (p) = 340 mu s, and the pulse-front duration is tau (f) = 15 mu s. The action integral of a current pulse of the first short stroke of artificial lightning with an amplitude of I (m) = 106 kD, which was obtained according to the IEC 62305-1-2010 standard, was J (a) = 3.03 x 10(6) D-2 s, and the electric charge that passed through the aforementioned load was q (l) = 52.2 C.
