It is becoming clear that compensated pulsed alternators (compulsators) are the preferred power supply for rapid-fire railgun systems. High efficiencies, inherently high repetition rates, and the elimination of high current opening switches are the primary advantages of compulsator-driven systems. The benefits and capabilities of these systems will be demonstrated in a project which is currently in the final stages of fabrication. The goals of this project are to accelerate a burst of ten, 80-g projectiles to 2 km/s at a 60 Hz rate of fire. Details of the compulsator design, the design, fabrication, and testing of system components, and proposed operation are presented.
