Abstract
The inductive energy storage (IES) generator has long been considered to be the most efficient system for energy usage in large pulsed power systems in the MA level. A number of parameters govern the efficiency of energy transfer between the storage capacitors and the load, and the level of current deliverable to the load. For a high power system, the energy storage capacitors are arranged as a Marx generator. The primary constraints are the inductances in the various parts of the circuit, in particular, the upstream inductance between the Marx and the plasma opening switch (POS), and the downstream inductance between the POS and the load. In this paper, we propose a new concept of the inductive line for energy storage (ILES), in which part of these inductances are replaced by suitable transmission line elements. Extensive parametric scans have been carried out on circuit simulations to investigate the effect of both the upstream and downstream transmission lines. Comparison with an existing IES generator shows that the ILES design offers a significant improvement in the maximum current and hence energy delivery to an inductive load.
