Type of Awards: SBIR Phase I with IEDC Subcontractor: University of Illinois Contract Numbers: N00014-09-M-0330 Agency: U.S. Status: Completed Periods: 8/20/2009 to 1/25/2010 Principal Investigator: J. R. Wells Abstract: The primary objective of the proposed work is to develop an unmanned underwater vehicle (UUV) power system architecture that is simultaneously scalable to multiple UUV sizes, light weight, affordable, and adaptable. This will be accomplished through the development of āsmartā power units (SPUās) that can be readily interconnected to provide distributed and coordinated power management for the UUV while providing battery cell balancing and charge monitoring. The SPUās will contain integrated power converter/controllers capable of providing for the vehicle hotel and propulsion loads, and compatible with multiple battery chemistries through the use of an automatic identification scheme. The SPUās will facilitate universal charging through a standard interface port, be modular enough to be deployed in a wide range of UUV sizes and dimensions, and be capable of communicating both with other SPUās and with the user using standard communication protocols. Deployment of the proposed SPUās will be greatly enhanced by accompanying software capable of rapidly sizing and configuring the modules for a given UUV size while minimizing size and...

O. Wasynczuk, E. A. Walters, PC Krause and Associates, Inc; H. J. Hegner, Naval Surface Warfare Center A new approach of automatically generating state-space models of power circuits and systems is presented. In this approach, the composite system state equations are established algorithmically given the standard node incidence matrix and elementary branch data (e.g. resistances, inductances, back emfās). The resulting state equations can be solved using a variety of numerical techniques or commercially available computer simulation programs. An example system consisting of a three-phase generator and rectifier load is used to illustrate this approach. Experimental verification is also provided.
