AbstractA robust power architecture and control scheme was developed in Phase I that provides a smooth power flow from fuel cell/battery to the load. The key element was a low cost bi-directional power converter control system. The proof-of concept of the system was validated for a 1st generation low power design and a 2nd generation high power design was developed. The design blocks for achieving the desired system performance, efficiency, stability and reliability were determined. In Phase II, the design blocks developed in Phase I will be upgraded to support high power and voltage loads (5kW at 48 VDC). The power systems transient response capability will be determined. A regenerative system will be considered and analyzed that is capable of supporting the 5kW bi-directional power converter. In Phase II a prototype hybrid power module that employs fuel cells, batteries, and efficient fast switching bi-directional power converter electronic system will be developed. The proposed targeted bi-directional electronic circuit should yield at least 95 % efficiency, capable to handle power of up to 5kw, and with ability to be connected in parallel to provide for higher power capabilities. The developed unit will be delivered to the Air Force at the end of the program.
