Compact High-Speed Isolation Device for MVDC Applications Navy SBIR FY2010.3 Sol No.: Navy SBIR FY2010.3 Topic No.: N103-226 Topic Title: Compact High-Speed Isolation Device for MVDC Applications Proposal No.: N103-226-0235 Firm: LMSW, Inc. 1900 Preston Road, #267-303 Plano, Texas 75093-3604 Contact: Patrick Antaki Phone: (972) 896-4937 Abstract: We will develop a novel high current (1-10kA) high voltage (10kVDC) electrical relay for use in modern Navy ship designs heavily reliant on DC electrical distribution. The switch utilizes an environmentally-friendly liquid metal as the primary switching element. This relay exhibits very low on-resistance, fast switching, no bounce, and significantly increased MTBF as compared with comparable electro-mechanical contactors. Benefits: A new type of electrical switch for high power applications will be developed, applicable to a host of uses, significantly increasing the reliability and reducing the cost of the switch. A key market is for renewable energy (wind, solar) applications in DC-to-AC inverters where connection to the 60Hz grid is needed. Return
