Ignatenko M. Increase of the energetical efficiency of discharge circuits of pulse high lightning current generators

The subject of the investigation is electromagnetic processes in high pulsed lightning current generators (PHLCG) with using of high-voltage energy storages; the goal of the investigation is increasing of efficiency of discharging circuit of PHLCG and creation of prototype of high-power high-voltage generator of lightning pulsed currents which will allow to conduct tests of large-sized technical objects in accordance with requirements of intergovernmental standard GOST 30585-98; methods of investigation are circuit theory methods, computer simulation, physical modelling, and conducting of experiments on created high-voltage generators PHLCG; scientific novelty - it is shown theoretically and experimentally that use of rationally chosen, corrective capacitances in developed PHLCG allows to increase (up to 20%) the value of amplitude of lightning pulsed current in resistive-inductive load; on the base of existing high-voltage equipment (generators: GIN-3 on 3 MV and GIN-4 on 4 MV), new high-efficient PHLCG was created in RDI "Molniya" of NTU "KPI" which allows to form aperiodic lightning current pulses with amplitude up to 100 kA of pulse form 2/50 mks on RL-load (R =0.1 Ohm, L =14 mkH); sphere of application - designing of new PHCLG generators and modernization of existing ones.
