Two-Staged Magnetocumulative Generators for High Impedance Loads

Two-staged magnetocumulative generators (MCG) with flux trapping for high impedance loads are considered. With an initial energy of several kilojoules, these generators have supplied energies up to 15 kJ into a 5 μH inductive load in about 15 μs. The total energy was amplified about 20 times. To get the open circuit voltage of the second stage under 60 kV, the working helix of the booster stage has a special set of pitches and increases the energy for ~30 μs. The second stage peaks the output electric pulse in the load. We also consider the possibilities of the MCGs designed for lightning action simulation on a grounded installation. In many cases, testing objects for lightning endurance is made at their locations. Compact, transportable, explosively driven MCG seems to be the most convenient equipment for this purpose.
