Parallel Operation of Compact, Efficient Turbogenerators for Robust Tactical Energy Independence

The intent of this project is to explore the feasibility of using a parallel connection strategy similar to a utility solution for the operation of multiple high speed turbo-generators in the 10 to 50 kW range. It is desired to connect the high frequency, 3-phase outputs of multiple turbo-generators in parallel to produce a single high frequency bus of significantly higher power, up to 500 kW. This single high power bus would then feed into a rectifier/inverter stage to produce a 60 Hz output which would be readily usable for both commercial and military loads. It would be very desirable for the 60 Hz converter stage to be based on multiple parallel converters each having the same power capacity as the turbo-generators. This would allow the number of operating turbo-generators and 60 Hz converters to be increased or decreased in step to control the total combined output power while maintaining redundancy and high efficiency in both stages.
