Abstract: Provided is a wireless power transmitter including a first coil disposed to transmit wireless power, a second coil disposed outside of the first coil to transmit wireless power, and a controller configured to determine whether to operate the wireless power transmitter in a magnetic induction mode or a magnetic resonance mode, control the first coil to operate in the magnetic induction mode and prevent the second coil from operating in the magnetic induction mode in response to the determination to operate the wireless power transmitter in the magnetic induction mode, and control the first coil and the second coil to operate integrally in the magnetic resonance mode in response to the determination to operate the wireless power transmitter in the magnetic resonance mode.
