POWER TRANSMITTING UNIT (PTU) AND POWER RECEIVING UNIT (PRU), AND COMMUNICATION METHOD OF PTU AND PRU IN WIRELESS POWER TRANSMISSION SYSTEM |
| 摘要 |
A communication method of a power transmitting unit (PTU) in a wireless power transmission system includes receiving a connection request signal from each of at least one power receiving unit (PRU), transmitting impedance change information of the at least one PRU to the at least one PRU, sensing a change in an impedance of each of the at least one PRU receiving the impedance change information, and determining whether each of the at least one PRU is connected based on the sensed change in the impedance. |

1. A communication method of a power transmitting unit (PTU) in a wireless power transmission system, the communication method comprising:
receiving a connection request signal from each of at least one power receiving unit (PRU); transmitting impedance change information of the at least one PRU to the at least one PRU; sensing a change in an impedance of each of the at least one PRU receiving the impedance change information; and determining whether each of the at least one PRU is connected based on the sensed change in the impedance. |
