Abstract
The results of optimizing a high-power switch that consists of a block of reversely switched-on dynistors with 50-mm diameter structures, a dynistor triggering unit, and a choke with a saturable core, which reduces the power of the triggering unit by creating a delay of a sharp increase in the main current during the flow of the control current having the opposite polarity, are presented. It is shown that the reduction of the traditional microsecond duration of the triggering action to several hundred nanoseconds, which is required for a significant reduction in the choke dimensions and inductance, does not lead to an increase in energy losses in dynistors if the control current has a sufficiently large amplitude and the magnitude of the triggering charge does not change. The design of an optimized switch having an inductance of ~200 nH and an operating voltage of 16 kV is described. The possibility of its long-term use for switching current pulses with an amplitude of ~100 kA that increase at a rate of ~30 kA/μs is shown.
