Advanced Power Distribution Systems

"We propose to extend our Power Node Control Center (PNCC) technology effort to develop advanced power distribution systems for the 120 VAC ship distribution system. The PNCC effort, a program sponsored by ONR, has concentrated on 450 VAC distributionsystems with loads under 300 kW. The 120 VAC distribution is a natural extension to the work already done. In our proposed concept, we propose to use MCTs as the solid state switches in AC switch topology to perform the switching and protection functionlisted in the proposal, while maintaining all the features of the PNCC. These features are modularity, more survivable systems, and continuous high power quality to the laod. In Phase 1 of this effort, we propose to design, build and test an all solidstate, 120 VAC power panel which demonstrates the switching and protection functions required in this solicitation. The successful completion of the proposed research effort will lead to a ship power distribution system that is more reliable, moresurvivable, and more affordable than today's systesm. A PNCC at the low voltage level will definitely have application in the industrial and aerospace markets as well as Naval and commerical ships."
