Abstract
A control device includes a control portion that controls a power supply portion that supplies power to a load based on received power received by a power receiving portion from a power transmitting device. In the case where the power receiving portion, after receiving a signal having a first frequency and a first duty from the power transmitting device, receives a signal having a second frequency that is different from the first frequency or a signal having a second duty that is different from the first duty, the control portion specifies an issued command based on a length of a reception period of the signal having the second frequency or the signal having the second duty.
