Research Institution
In Phase I of this SBIR, Diversified Technologies, Inc. (DTI) developed a design for a compact, rugged, capacitor-charging converter for the Navy Electromagnetic Railgun (EMRG) program. Evaluation and testing of critical design elements were completed, and prototype subassemblies are planned under the Phase I option. This development will allow production of two prototype units in Phase II. To date, we have made significant progress toward this goal through a review of system requirements, initial design of the prototype assembly, and analysis and laboratory tests of critical subassemblies. The primary goals of the program were determined in a detailed Requirements Document developed with the Naval Surface Warfare Center (NSWC), defining the specifications for the electrical, mechanical, and environmental performance for our design. Based on our work to-date, the system under development will meet or exceed all specificationsa power converter supporting up to 325 kJ/s peak charging capability, over 300 kW of average power, and with power density greater than 2 MW/m3. This design verifies that all required components from DTIs DC supply may be packaged in an assembly one-eighth the size of our commercial module without sacrificing performance or system reliability.
