Fast calculation model for helical magnetic flux compression generators

In this paper, an equivalent circuit calculation model of the single stage helical magnetic flux compression generators is developed. The inductance and resistance of the generator are formulated based on the assumption of zero-dimensional model. A calculation code is programmed to compute the generator parameters and the change of current, inner voltage, resistivity and temperature during the charging and operating period of the generator. The calculated results prove that the model can provide an accurate prediction for designing magnetic flux compression generators.
