Compact generators of high-power fast-rising pulses with closing switches in the form of reversely switched dynistors.

This paper presents the results of a study of reversely switched dynistors (RSDs) with an operating voltage of 2.3 kV and a structure diameter of 12 mm in an unconventional mode, when they commutate current pulses with very short durations (a few microseconds). In this mode, we studied the dependence of the switching energy loss on the amount of charge that passes through the RSDs during the flow of the control current, which is reversed with respect to the main current.

Silicon dynistors with subnanosecond switching times.

High-voltage silicon dynistors, which are turned on by means of initiating a shock ionization process in silicon, have unique capabilities with regard to switching of current pulses of a nanosecond duration. This paper describes the design of shock-ionized dynistors (SIDs) optimized to reduce the energy loss during switching. The use of these SIDs allows for a twofold reduction in the triggering generator's power consumption.
