This work describes an inductive energy storage scheme intended for
power multiplication at mega-Ampere currents. The key power multiplication
element of the scheme is an opening switch generating the voltage of
inductive origin. The switch represents an additional volume with
magnetically accelerated solid-state or plasma conductor between the
generator and the load. Motion of the conductor increases the inductance
of the volume. A sufficiently fast increase of this inductance at the end
of magnetic energy storage time ensures power multiplication. A critical
requirement for the accelerated conductor is the possibility of temporal
profiling of the inductance increase. A proof-of-principle experiment at
GIT12 shows that such profiling is possible. We suggest a simple analysis
of the scheme efficiency and illustrate this analysis for a
multi-mega-Ampere class generator. The scheme is alternative to existing
inductive energy storage technologies for pulsed-power conditioning at
high currents.
