|Title:||Reversed Switch-On Dynistor Switches of Gigawatt Power Microsecond Pulses|
|Abstract:||A high-power (250 kA and 25 kV) compact switch based on an assembly of reversed switch-on dynistors (RSDs) connected in series and a coaxial saturable-core choke, which is necessary for their effective switching, is described. An essential feature of this switch is a drastic reduction of the duration of RSDs control pulse, which allows using minimum dimensions and low inductance saturable core choke and obtain high rise rate (more than 30 kA/µs) of the switched current. The increased RSDs control pulse amplitude and rise rate that are required for RSDs switching on by reduced duration triggering pulse are attained by using a fast switch based on new type semiconductor devices deep-level dynistors (DLDs).|
