Compact, Flexible Integrated Power Node Center for Direct Current Distribution

DTI proposes an air-cooled galvanically-isolated, high power density integrated power node center for DC distribution. The inputs will be 440 VAC, 60 Hz and/or 1000 VDC and the outputs will be 440 VAC, 60 Hz, 440 VAC, 400 Hz, or 650 VDC, among others. The output will seamlessly transfer among inputs or outputs. The high power density of 2 MW/m3 can only be achieved by high frequency switched mode power supplies (SMPS) which DTI is well-experienced with. During Phase I, DTI will develop and demonstrate a high power isolation inverter capable of full power while meeting the galvanic isolation and insulation goals. The unit will be air-cooled, and will interface to sources and loads, as appropriate. A 3-phase active power-factor input module with controls will be also be demonstrated. Performance characteristics will be evaluated and reported to the Navy. In Phase II, DTI will work with the Navy to perfect the mechanical and electrical interfaces required for mission-critical ship-born electrical subsystems, ultimately leading to a full form-fit-function prototype for evaluation in the field by Navy sponsors.
