A compensated pulsed alternator (compulsator) is an attractive alternative to the homopolar-inductor switch system as a power source for a rapid-fire railgun. The design of the compulsator and a few other components of the system are presented. Results of the tests on various components of the system are also discussed. The system is designed to accelerate 80-g projectiles to 2 to 3 km/s at 60 Hz. The rapid-fire gun system consists of several components. The compulsator is the power source and provides current pulses to the injector and the railgun. The injector, which is a high inductance gradient EM gun, accelerates the projectile from rest to an initial velocity of 200 m/s in order to reduce damage at the breech of the rails. The railgun has a parallel rail geometry and accelerates the projectile from the injection velocity to a final velocity of 2 to 3 km/s. The rails are directly connected to the compulsator without a switch, whereas the injector is triggered with an ignitron.
