Empirical models have been reported earlier to estimate the resistivity of electrically exploded conductors (EECs) as a function of geometrical parameters only, such as cross-sectional area and length. Since inductance of inductive energy storage system (IESS) also affects the resistivity of EEC, similar models but with modified empirical coefficients are reported here by including inductance of IESS which makes them applicable for the prediction of resistivity of EEC at different time-scales/systems. Using curve fitting on experimental data reported earlier, methods to evaluate modified empirical coefficients are presented. Circuit simulations carried out using these models are able to predict the current as well as voltage profile in EEC and load for different inductances of IESS. Experiments have been carried out to validate the results predicted by simulation and are found to be in close agreement. [ABSTRACT FROM AUTHOR]

This paper is aimed at finding the effect of varying inductive energy storage systems’ (IESSs) inductance on resistance of an electrically exploded conductor-based opening switch and profile of current transferred into load, which has not yet been fully understood. Based on experimental results obtained, it is observed that when the inductance of IESS is varied, the magnitude of load current changes so as to conform to the magnetic flux conservation law but its rise time remains unchanged. Resistance of the opening switch and energy deposited in it has been estimated using recorded voltage and current waveforms. It has been found that with increasing inductance of IESS, the resistance of switch increases, whereas energy deposited in it decreases. Using these estimated values of energy, a possible explanation of observed behavior in resistance is presented. Effect of a mismatch between the inductance of IESS and load is seen to only affect the energy transfer efficiency or magnitude of load current but not its rise time emphasizing the novel finding that for a given load, the rise time of load current is independent of the inductance of IESS.
