9. A transmitter for transmitting wireless power comprising:
-
a transmission side communication unit, wherein the transmission side communication unit transmits a first control signal to a reception side communication unit of a receiver, receives a second control signal from the reception side communication unit, the second control signal including information of a charged amount of a battery of the receiver, and compares the charged amount of the battery and a predetermined value to adjust a transmission period of the first control signal, wherein, when the charged amount of the battery of the receiver is equal to or larger than the predetermined value, the transmission period of the first control signal is reduced, and wherein, when the charged amount of the battery of the receiver is less than the predetermined value, the transmission period of the first control signal is increased. - View Dependent Claims (10, 11, 12, 13, 14, 15)
