Abstract: DTI is proposing a simple reliable passive solution to power factor correction for the F/A-18 Hornet Super Hornet versions C/D/E/F and G. We propose to design a two-tap, common-core, passive, 3-phase inductor comprised of innovative tri-cores. We will compare ferromagnetic materials, conductive materials, inductor configurations, and switch types and perform a trade study of total weight vs total losses. Initial studies indicate the corrector supplies excellent power factor performance across the full load range: 20 kVA to 65 kVA remaining between 0.88 and 0.97 lagging. The inductor will be designed for all relevant environment and interface specifications. In Phase I, we will fabricate and demonstrate a form-fit-function breadboard power factor corrector at full rated power capable of correcting leading power factor to a target of 0.93 lagging in compliance with military standards. In the Option effort, we will optimize the mechanical, thermal and packaging aspects of the unit. In Phase II DTI will work with the Navy to ruggedize the system, and to integrate the mechanical and electrical interfaces into the target air frame. Finally in Phase III, DTI and partners will work to transition the technology to the Navy directly and to any potential commercial customers.
Benefits: The Phase I Base effort will prove conclusively the feasibility and demonstrate the benefits of the proposed innovative power factor corrector electrical performance through simulation and testing. The Option will allow us to optimize and verify mechanical, thermal and packaging performance. The Option will naturally expand into a Phase II effort to design and fabricate a power factor corrector simultaneously meeting all prototype requirements. DTI?Ts development of a power factor corrector will feed several initiatives in the future. The compact design of this unit offers the potential to drive our power supply systems with more compact designs, which will benefit a range of military, industrial, and high energy physics customers. The design could spread throughout our line of high power supplies.
