The Center for Electromechanics at The University of Texas at Austin (CEM-UT) has carried out several major experimental programs using homopolar generator (HPG)-charged inductors; namely, the fast discharge experiment (FDX) field coil experiments, the General Dynamics single-shot railgun, and the compact homopolar generator/inductor (CHPG/I) experiments. As a result of this experimental and theoretical work, CEM-UT experience with modelling and predicting the performance of HPG-charged inductive energy store systems has been refined. This paper presents techniques found useful for estimating and modeling of HPG inductive energy store systems. A 3000 lbm liquid nitrogen cooled, aluminum inductor, rated to store 3.1 MJ at 1.0 MA, was built to provide power conditioning for different electromagnetic launcher applications. The modeling of these experiments, the theory developed to predict the results, the tests performed, and the comparison of the results obtained from tests with the theoretical assumptions led to a refinement of the techniques for designing and fabricating HPG charging inductors. An application of such modeling was used in the design and fabrication of the group of six HPG which will constitute the 60-MJ power supply installed at the new CEM facility for research in pulse power technology at Balcones Research Center. The inductors in which the power supply is discharging are optimized using results from the mentioned experiments.
