1. A method of synchronization control of a power transmitting unit (PTU), the method comprising:
- network-connecting a first PTU to a PTU operating in a slave mode by setting an operation mode of the first PTU to a master mode; and
transmitting a signal from the PTU operating in the slave mode to a power receiving unit (PRU) by controlling, by the first PTU, either one or both of a communication time and a communication frequency of the PTU operating in the slave mode, such that the signal transmitted from the PTU operating in the slave mode and a signal transmitted from the first PTU do not overlap.

Abstract
A method of synchronization control of a power transmitting unit (PTU) includes network-connecting a PTU to a PTU operating in a slave mode by setting an operation mode of the PTU to a master mode, and transmitting a signal to a power receiving unit (PRU) by controlling either one or both of a communication time and a communication frequency of the PTU operating in the slave mode.

15. A method of synchronization control of a power transmitting unit (PTU), the method comprising:
-
network-connecting a first PTU to a neighboring PTU operating in a master mode; setting an index of the first PTU and an index of the neighboring PTU operating in a slave mode based on a sequential order in which the first PTU and the neighboring PTU operating in the slave mode were network-connected to the neighboring PTU operating in the master mode; comparing the index of the first PTU to the index of the neighboring PTU operating in the slave mode in response to removal of the neighboring PTU operating in the master mode from the network-connection; and setting an operation mode of the first PTU to the master mode in response to a result of the comparing being that the index of the first PTU is higher than the index of the neighboring PTU operating in the slave mode. - View Dependent Claims (16)

17. A method of synchronization control of a power transmitting unit (PTU), the method comprising:
-
network-connecting a first PTU to a PTU operating in a slave mode by setting an operation mode of the first PTU to a master mode; and synchronizing an operation of transmitting a signal from the PTU operating in the slave mode to a power receiving unit (PRU) with an operation of transmitting a signal from the first PTU to the PRU. - View Dependent Claims (18, 19, 20)
