1. A transfer system comprising
a plurality of transfer path units that form a transfer path, on which a transferring body moves, to cause the transferring body to move by giving power to the transferring body; and
control circuitry configured to control each of the plurality of the transfer path units, wherein
each of the plurality of the transfer path units includes:
a drive unit to generate the power; and
an inverter circuit that includes a switching element to supply, to the drive unit, electric power obtained through electric power conversion by switching of the switching element, and
the circuitry is configured to control at least one of the transfer path units in a portion of the transfer path where the transferring body is absent to stop the switching in the inverter circuit.
