WIRELESS POWER RECEIVING APPARATUS AND POWER CONTROL METHOD THEREOF RELATED APPLICATIONS
First Claim
1. A wireless power receiving apparatus, comprising:
- a secondary core to receive a wireless power signal from a primary core of a wireless power transmission apparatus;
a magnetic sensor to detect a magnetic field value generated from the primary core; and
a receiving controller to transmit an error code to the wireless power transmission apparatus via the secondary core if the detected magnetic field value from the magnetic sensor is lower than a reference magnetic value and communication with the wireless power transmission apparatus is available.
