1. A system for supplying electric power to components of an agricultural harvester, the system comprising:
a power storage device;
at least one of a base cutter assembly, a chopper assembly, a primary extractor, a fan, or an elevator drive;
a first bus electrically coupled to the power storage device and the at least one of the base cutter assembly, the chopper assembly, the primary extractor, the fan, or the elevator drive such that the first bus supplies electric power from the power storage device at a first voltage to the at least one of the base cutter assembly, the chopper assembly, the primary extractor, the fan, or the elevator drive;
at least one of a crop divider, a topper assembly, a gatherer drum, or a secondary extractor;
a converter electrically coupled to the first bus; and
a second bus electrically coupled to the converter and the at least one of the crop divider, the topper assembly, the gatherer drum, or the secondary extractor such that the second bus supplies the electric power at a second voltage to the at least one of the crop divider, the topper assembly, the gatherer drum, or the secondary extractor, the second voltage being less than the first voltage,
wherein the converter reduces the first voltage of the electric power received from the first bus to the second voltage for delivery to the second bus such that the electric power from the power storage device is supplied to the at least one of the crop divider, the topper assembly, the gatherer drum, or the secondary extractor through the first bus, the converter, and the second bus.
