Research Center Blvd., Suite 209 Fayetteville, Arkansas 72701-7174 Contact: Roberto Schupbach Phone: (479) 443-5759 Web Site: www.apei.net Abstract: Present high power density Si-based systems are severely limited by the electrical and thermal performance of active and passive components as well as electronics packaging technology. As a result, the next-generation of radar power supply systems require a new and revolutionary power electronics technology that delivers far superior efficiency, response time, thermal performance, and miniaturization capability. This Small Business Innovation Research project seeks to develop high-voltage (up to 1000 VDC), highly efficient (>90%), and compact (>200 W/in3) next-generation radar power supplies utilizing emerging Wide Band-Gap (WBG) power devices in conjunction with advanced non-linear control and high power density packaging techniques. The new WBG-based radar power supply technology will be capable of fast response time (rise and settling times < 10 �s) and reducing the output stored energy to less than 1 Joule. Benefits: The customers for the specific technology being developed in this SBIR program will be the Navy and the aerospace industry. The customers for WBG power electronic products are those requiring high performance systems such as: military electronics (e.g., aircraft, rockets, military weapons' platforms, combat vehicles, etc), aerospace (e.g., satellites, spacecraft, commercial airplanes, etc.), automotive (e.g., electric and hybrid-electric vehicles and subcomponents of more-electric vehicles), and petroleum and gas exploration (e.g., down-hole drilling, exploration logging tools, etc.). Hence, customers for this technology in the short-term are: (a) Federal government (US military and NASA), (b) defense contractors (Northrop Grumman, Lockheed-Martin, Raytheon, Boeing, etc.), (c) aerospace companies (Moog, Hamilton Sundstrand, Aerojet, etc.) and (d) energy conglomerates and exploration (Siemens, Halliburton, Conoco, and Oyo Geo Space) who provide a path to sell technology for government systems.
