1. Electrification of the Future US Navy Warships
Rasoul Hosseini, Robert Cuzner
Office of Naval Research Award Number N

2. Motivation United States of America is a valuable asset
Surrounded by water
It makes sense to invest in Navy!
Continuous development is needed
Statue of Liberty

3. New Destroyer is Needed
“In FY2030, the DON plans to start building an affordable follow-on, multi-mission, mid-sized future surface combatant to replace the Flight IIA DDG 51s that will begin reaching their ESLs [Estimated Service Life] in FY2040.”
Report to Congress on the Annual Long-Range Plan for Construction of Naval Vessels for FY2015
Desired New Features:
1- New weapons
2- Easier maintenance
Flight IIA DDG 51s Destroyer

4. New Weapons and Systems
Navy has invested in New weapons:
Electromagnetic Railgun
BAE systems, General Atomics
Solid State Laser weapon
NAVSEA, Northrop Grumman
These weapons require pulsed
DC power (10s on MW)
Other New Equipment
High power sensors
High power Radars Lockheed Martin
Electromagnetic Railgun
High Power Solid State Laser

5. Power Management
Generation and Consumption of power are not following the same pattern!!

6. Medium Voltage DC Architecture
Generation
Distribution
Conversion
Storage
Pulse Forming
Connections
Loads:
Propulsion, Hotel Loads,
Weapons, sensors, radars
Computer, communication and navigation

7. Design Considerations
Modular → easy maintenance Scalable → For future development Efficient → lower fuel less cost Power dense → Space Is limited Electromagnetic Compatible → Integration Safe → Its High Voltage DC! UWM, UA, MSU, Eaton, FSU, Virginia Tech Least Replicable Unit (LRU) Power Electronic Building Block (PEBB) → Universal Converter What is the voltage? What is the power? What are the switches? COST?!!…. PEBB 1000, PEBB 6000, SiC MOSFET vs IGBT?? Open Questions! UWM, GE, DRS, Virginia Tech, USC

12. Future Works
Perform meta-modeling approach for all converters, each zone and eventually the system
Use Multi-Objective Optimization techniques to find the optimum design
Develop Simulation Modules which are compatible with various simulation environments
Perform HIL simulation for the whole system model
Continue on developing the hardware for experimental tests
