Gen-sets

This article describes a proof-of-concept development for a 7.5 kW gen-set in a family of military gen-sets in the 5 to 60 kW range. Several power electronic converters have been implemented in the design of this proof-of-concept gen-set that is lighter, smaller, and more fuel efficient than conventional fixed-speed gen-sets. The unit also has the flexibility of several selectable voltage and frequency options that greatly reduces the inventory logistics burden for a family of different unit types and sizes. With integrated controls and power electronics, the gen-set is able to run at its most efficient condition to minimize fuel consumption. It would also be possible to control the gen-set such that it ran at other different optimized conditions such as: maximum headroom for supplying load transients; most audibly quiet; and least polluting for certain emissions.
