An electromagnetic gun power supply as a component of an electric ship power system
MetadataShow full item record
An electromagnetic gun provides a new component that must be integrated into the power system of an electric ship. An interesting topology for the power supply is a set of pulsed alternators with sufficient energy stored in the kinetic energy of the rotors to power the shot. In this configuration, when no shot is required, the machine topology is analogous to that of a flywheel battery used to provide ride-through capability and improve power quality in land-based power systems. This paper expands upon earlier published work showing worst case perturbation to the power system, in this approach, and the use of the pulsed alternators as high-energy active filters to improve power system performance.
