COIL STRUCTURE FOR INDUCTIVE AND RESONANT WIRELESS CHARGING TRANSMITTER AND INTEGRAL CONTROL METHOD FOR THE SAME
First Claim
1. A wireless power transmitter, comprising:
- 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.

8. A method of transmitting wireless power in a vehicle, the method comprising:
-
detecting at least one terminal capable of receiving wireless power in the vehicle and determining whether each detected terminal supports magnetic resonant wireless power reception or magnetic inductive wireless power reception; providing magnetic inductive wireless power transmission to the terminal by turning on a first coil disposed to transmit wireless power and turning off a second coil disposed outside of the first coil in response to determination that a magnetic induction mode is needed; and providing magnetic resonant wireless power transmission to the terminal by integrally operating the first coil and the second coil in response to determination that a magnetic resonance mode is needed. - View Dependent Claims (9, 10, 11)
