Abstract
For some applications of magnetic flux compression generators, shorter pulse widths, with associated higher voltages and power levels, are required.We have developed a family of small, tapered stator generators that begin to address these requirements. Specifically, the three versions of these FCGs developed use stator angles of 100, 120, and 130 with respect to the generator axis. These three respective angles resulted in increasingly larger phased closure velocities. The armature diameter is 2.54 cm, and the armature expansion ratio is about 2:1. The shortest dI/dt pulse, in terms of Full-Width-Half-Maximum (FWHM), produced is 398 ns in the current derivative. The peak value for dI/dt is about 3.5 × 1010 amps/sec.
