600 kJ Power Supply System and Its Application in Railgun

A 600 kJ power supply system for the railgun system is presented. A capacitor bank is used as its primary power. Effective energy transfers from the primary power to a railgun through a transform circuit with inductor and crowbar. Explosively driven, metal-to-metal contact, solid dielectric switches have been developed as master switch and crowbar. An empirical medal to describe the switch resistance time-dependence has been proposed. Experimental results show that the system operates well.
