Ｈigh-frequency analysis on the initial electrical performance of a helical magnetic flux compression generator

The distribution of the current density in the wire and induced current density within the armature for a Helical magnetic flux compression generator(HMFCG) are studied based on the solutions of the current and magnetic field diffusion equations,The HMFCG inductance and resistance are calculated analytically during the transient process, and the agreement between the numerical one and the experimental results are quite satisfactory．
