A High-Current High-$di/dt$ Pulse Generator Based on Reverse Switching Dynistors

A scheme for a high-current high-
di
/
dt
pulse generator is described, which incorporates an assembly of reverse switching dynistors (RSDs), a magnetic compression section, a trigger circuit based on a step-up saturable pulse transformer, and an additional RSD unit with a small working area. The generator, with an operating voltage of 10 kV, can switch a 108-kA pulse current with a full width at half maximum of about 65-
mu
s duration, a
di
/
dt
of 8.66 kA/
mu
s, and a jitter of less than 60 ns. The charge transferred and action are about 6 C and 0.53 MA
²
s, respectively.
