Electric Discharge Device for Destruction of Large-Sized Objects Based on Reverse Switching Dynistors

The report presents the results of research aimed at creating a highly efficient device based on reverse switching dynistors (RSD), which ensures the destruction of large objects by powerful electrical discharges in water. The operating principle of the RSD developed at Ioffe Institute (St. Petersburg, Russia) and physical processes that make it possible to create powerful shock waves in water that can destroy concrete and stone blocks with a size of ~ 1 m³ are described. A schematic electrical diagram of the developed RSD device is shown. The principle of its operation is described. The design of a RSD device that ensures the destruction of a large object is shown. The oscillograms of the output voltage pulses and discharge current obtained during testing of the RSD device are presented. Photographs of destroyed concrete blocks and large stones obtained using the developed RSD device are shown. The prospects for further work in this direction are considered.
