Electric Generator Sets with Improved Fuel Consumption. Our project "High Frequency Alternator, Power Frequency Conversion (HFA-PFC) Technology for Lightweight Tactical Power generation" won a contract with the Department of Defense. Our contract was successfully completed. We offered a new approach to improve fuel consumption of existing diesel generators. For instance, the fuel consumption of a conventional military 60 kW diesel generator set, which is shown at left, can be reduced up to 41%.
