DEVICE AND METHOD FOR CONTROLLING WIRELESS POWER SIGNAL IN WIRELESS POWER TRANSMISSION DEVICE
First Claim
1. A method of controlling a wireless power signal in a wireless power transmission device, comprising:
- transmitting an object detecting signal via a transmission coil of the wireless power transmission device;
receiving an object response signal in response to the object detecting signal via the transmission coil;
transmitting the wireless power signal to a wireless power receiving device via the transmission coil based on the object response signal;
detecting a voltage or a current of the transmission coil; and
changing the wireless power signal when a phase value of the voltage or the current of the transmission coil is changed by more than a predetermined value.
