Novel Power Supply for Pulsed Power Application
MetadataShow full item record
Railgun muzzle flash, or post-fire arcing, is a major concern to the Navy because of the potential thermal stress associated with post-fire arcing. In this project a new railgun power supply was compared to the thyristor-based one, which is the state of the art. Quantification of the post-fire rail energy reveals that the proposed buck-boost converter topology is better suited for the railgun than the thyristor-based one, particularly at minimizing the post-fire muzzle energy. The minimization of the post-fire energy allows for an extended rail life and potentially longer usage.
