HFA-PFC Systems for Tactical Mobile Electric Power Systems

摘要

Tactical Mobile Electric Power Systems have the potential for significant weight savings. An average decrease of 87.2% may be achieved through the use of a high frequency alternator - power frequency converter combination, when compared to the standard 1800 rpm fixed speed 60 % generator. A potential 48.6% decrease is possible when considering the complete engine generator set. A gearbox provides the necessary speed increase for high speed/high frequency operation. This also provides an oil management system for cooling equipment and ultimately providing a higher power density system. Integration of additional functions, such as a starter generator, provides for added weight savings. The approach may be extended to a modular system concept to reduce the number of unique system components, and accommodate growth requirements. Additional new features such as variable speed operation of the engine may be integrated to reduce the average fuel consumption, acoustic emissions and IR emissions when operating at less than full load. This will assist in improving engine life span, and potentially reducing scheduled maintenance.
