摘要：

Two versions of a switch circuit based on an assembly of reverse switch-on dynistors (RSDs) with a 25-kV operating voltage connected in series are described. Their main feature is a decrease in the device dimensions as a result of introducing two successively triggered low-power dynistor units into the control circuit and assembling several RSD structures in a common ceramic housing. The first circuit version is used in the discharge circuit of the capacitive energy storage in the operation into a mismatched load and can switch alternating pulses with a 750-mus duration with amplitudes of the first pulses of the forward and reverse currents of 130 and 15 kA, respectively. The second version employs the crowbar regime and makes it possible to form unipolar current pulses with a 190-kA amplitude and a 500-mus duration in the load circuit.
