OPERATIONAL EM RAILGUN / 700k AMP SWITCHED CAP PULSED POWER SUPPLIES
This is a fully operational "turn-key" electromagnetic railgun system capable of launching a projectile to well over 3900 feet per second. The
system is based on a capacitor-discharge pulse-forming network (PFN). Capacitors are charged to 400V. To fire the gun, the capacitors are
discharged into the rails by closing thyristor switches in rapid succession. There are 32 capacitor-thyristor switch modules that can
each be individually controlled. The current profile and projectile acceleration is programmable. The system includes an electromechanical
loader to inject the projectile (armature) into the barrel at the breech end. It also includes an arc-flash chamber with integrated catch
assembly to contain the blast and projectile. A cabinet with power supplies and controls hardware is included. Manuals and safety equipment
are also included. From loading to firing - everything is controlled from a remote PC terminal (included). This system can be used with 1 PFN cabinet (described below), or with 2 PFN cabinets for the full 1 mega amp capacity.
