MAINSTREAM ENGINEERING CORP — Department of Defense SBIR Phase I: N181-069

Description

Navy ships currently operate two independent power systems at 60Hz and another at 400Hz. These two power systems are redundant wasting spacing. A better approach is to utilize 60 Hz equipment and place 400Hz equipment at the load site. In addition, future Naval ships will also utilize dc distribution, providing another power distribution bus to service loads. Thus a local power conversion solution for current and future Naval vessels is necessary. Mainstream proposes a modular, ultra-power dense integrated power node center with reconfigurable output types and power levels. The proposed solution will increase the power density of naval power electronics to levels required to be strategically located, lower maintenance cost, and increase reliability over current solutions. In Phase I, Mainstream will design and optimize the power electronics hardware, thermal management system, and controls. The power electronic hardware will also be demonstrated. In Phase II, Mainstream will demonstrate a full-scale prototype in a simulated naval power system.
