Utilization of an Iterative Curve Fitting Technique for Determination of Switch Circuit Parameters

This paper presents a nonlinear curve fitting technique to be used in pulsed power applications. Specifically, experimental results from the University of Missouri Terawatt Test Stand are analyzed. The concept is presented as a way to determine resistance and inductance of a gas switch and experimental data is discussed. Several examples are given along with a brief discussion of results for a multichannel 3 MV gas switch.
