1. A power system comprising:
a first pulley;
an engine configured to output a rotational force at a first rotational speed to rotate the first pulley;
a belt-driven component;
a generator comprising a generator shaft and configured to convert mechanical power driving the generator shaft to electric power, wherein the generator shaft operates as an intermediary between the engine and the belt-driven component;
a second pulley fixedly coupled to the generator shaft and drivingly coupled to the first pulley via a first belt, wherein the second pulley is configured to rotate the generator shaft at a second rotational speed based on the first rotational speed;
a third pulley configured to drive the belt-driven component; and
a fourth pulley fixedly coupled to the generator shaft, the fourth pulley having a first diameter that is greater than a second diameter of the second pulley, wherein the second pulley is configured to drive the fourth pulley via the generator shaft, and wherein the fourth pulley is configured to drive the third pulley at a third rotational speed via a second belt, wherein the fourth pulley comprises an integrated clutch mechanism.
