Research Institution

In Phase II, Diversified Technologies Inc. (DTI) and subcontractor Neeltran, Inc. propose to develop a compact, 60 Hz, 440 Vrms, 150 kVA, militarized, 1:1 galvanic isolation transformer, meeting and exceeding the original Phase I required power level of 112.5 kVA. The main objective is to reduce the size and weight of militarized single-core three-phase transformers for use within Navy shipboard power distribution systems, while meeting the Navy-specific requirements for shipboard use.  DTI and Neeltran will update the specification, design, and power level as desired by the Navy. DTI will fabricate and electrically demonstrate four transformers, and prepare the units for qualification testing, achieving TRL 6. In Phase II Option 1, DTI will complete Environmental Qualification Testing on three units. The transformers will be validated through testing to MIL-STDs by an independent test facility.  In Phase II Option 2, DTI will deliver, install, and fully test a qualified final isolation transformer shipboard or at a U.S. Navy test facility, thereby achieving TRL 7. Together, DTI and Neeltran have the electromagnetics expertise, design capabilities, experience with the Navy procurement process, and domestic transformer manufacturing facilities required to develop and produce compact and lightweight isolation transformers. DTI has extensive experience delivering advanced power electronics systems, especially transformer-based systems, to the Navy. DTI has directly transitioned products from three Navy SBIRs into production and deployment. Our Phase III revenues from sales to the Navy, Air Force, and commercial customers based on SBIR technology have allowed us to double our revenues over the last five years. As a result, DTI is one of the highest-rated firms in the country with respect to SBIR commercialization success.
