Abstract :
Inductive energy storage (IES) generator has long been considered to be the most efficient system for energy usage in large pulsed power system 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 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 POS, and the downstream inductance between the POS and the load. In this paper, we consider the effect of replacing part of the upstream inductance with a transmission line and introduce the new concept of an inductive line for energy storage (ILES). Extensive parametric scans have been carried out on circuit simulations to investigate the effect of this upstream transmission line. A model is developed to explain the operation of the ILES design based on the data obtained. Comparison with an existing IES generator shows that the ILES design offers a significant improvement in the maximum current and hence energy delivered to an inductive load.
