Abstract
A railgun accelerator system powered by alternating current (AC) is disclosed. In one form, the system advantageously uses multiples of six railguns in parallel, allowing velocities of around 100 miles per hour to be imparted to a carriage of mass around 6000 pounds. Three phase AC power from a domestic grid or from a similar source may feed multiple power points along the length of the accelerator.
