Abstract: | An analytical scheme on the initial transient process in a simple helical flux
compression generator, which includes the distributions of both the magnetic field
in the hollow of an armature and the conducting current density in the stator, is
developed by means of a diffusion equation. A relationship between frequency of the
conducting current, root of the characteristic function of Bessel equation and decay
time in the armature is given. The skin depth in the helical stator is calculated
and is compared with the approximate one which is widely used in the calculation of
magnetic diffusion. Our analytical results are helpful to understanding the
mechanism of the loss of magnetic flux in both the armature and stator and to
suggesting an optimal design for improving performance of the helical flux
compression generator. |
