Transformer Energy Output Magnetic Cumulation Generators

Abstract

There are many applications for magnetic cumulation generators (MCG) with required load inductance and resistance much greater than the final inductance and resistance of a MCG. Transformer coupling may be used in this case to match the load and MCG. Such coupling proves useful to cascade MCG’s, to sharpen load current pulse, to achieve high voltage and so forth.

Performance of transformer MCG’s with various types of loads as well as transformer coupling parameters for particular devices are reported. A description is given of some construction designs for transformer units which make use of multiturn coils in toroidal and cylindrical geometry and coaxial cable coils.

Helical-coil cone-coaxial MCG devices combined with cable transformer blocks are described. The helix inner diameter is ranging from 40 to 320 mm. Test experimental results are given. The maximum energy output on an inductive load of 1.5 μH rises up to 20 MJ at instantaneous power of about 0.5 TW. Several matching transformer block designs provide for MCG efficient performance with inductive loads of up to 100 μH or resistance of a few ohms at about 400 kV voltage.

A cascade generator providing energy amplification factor of about 10⁴ has been built on the basis of transformer matching MCG’s. If the latter is combined with a cascade generator of 1 kJ output energy, energy amplification factor of about 10⁸ may be achieved.
