Detection and Mitigation of Electrical Faults in Medium Voltage DC (MVDC) Architectures Navy SBIR FY2009.1 Sol No.: Navy SBIR FY2009.1 Topic No.: N091-050 Topic Title: Detection and Mitigation of Electrical Faults in Medium Voltage DC (MVDC) Architectures Proposal No.: N091-050-0110 Firm: Diversified Technologies, Inc. 35 Wiggins Ave. Bedford, Massachusetts 01730 Contact: Ian Roth Phone: (781) 275-9444 Web Site: www.divtecs.com Abstract: In this effort, DTI will refine the specification and scope of a DC breaker development, and prepare for the Phase II effort, which will comprise fabrication and delivery of an engineering development model for evaluation by US Navy laboratories. We anticipate that the value of such a solid-state direct-current breaker will ultimately lie more in the enhanced capabilities of the entire shipboard power system that this advanced technology enables than in the capabilities of the breaker taken alone. Benefits: From this baseline, DTI will be positioned to expand this solid state technology into larger markets and more complex applications, including bus transfer switches for both AC and DC power systems, Flexible AC Transmission Systems (FACTS) power control systems, and a wide range of related power control applications. This will allow DTI to move from a strong niche player in our current specialized pulsed power markets into a much larger market encompassing power distribution and control. The circuits and systems developed under this SBIR, although centered around commercially available devices such as IGBTs, will place DTI in an ideal position to incorporate new switches as they are developed and commercialized.
