Modular design of a 100 GW, 10 kJ, charged dielectric line driven pulsed transformer

Abstract

The pulse obtainable from a dielectric-charged line-driven pulsed transformer is discussed. In the proposed design, charged cables (in the normal configuration as well as in the Blumlein configuration) are used as intermediate stores to take advantage of the extremely high energy densities in the electrostatically stressed dielectric insulators. The proposed conceptual design is a 1 MV, 100 GW, 10 Omega , 100 ns, 10 kJ pulser. It is concluded that with a more inductive transformer (i.e. with a core or possibly a larger transformer), it would be possible to extend the output pulse, thereby increasing the output energy. It was found during the design that the Blumlein pulser is more difficult and more expensive to construct than the conventional charged cable pulser.<>
