Low Noise Power Systems and Associated Method

Abstract:

Power systems having reduced operating noise and associated methods are disclosed. An example non-synchronous power system includes an engine, a generator, a driveshaft, and a pulley system. The engine may be configured to output, to the driveshaft, a rotational force at a first rotational speed. The pulley system may be configured to receive the rotational force at the first rotational speed at a first pulley and to output the rotational force at a second rotational speed via a second pulley. The first and second pulleys may be drivingly coupled to one another at a fixed pulley ratio. The generator may be configured to receive the rotational force at the second rotational speed to generate electric power.
