Wireless power receiving apparatus and power control method thereof related applications

摘要

A wireless power receiving device and a power control method thereof. The wireless power receiving apparatus, includes: a secondary core configured to receive a wireless power signal from a primary core of a wireless power transmission apparatus; a magnetic sensor configured to detect a magnetic field generated from the primary core; and a receiving controller configured to transmit an error code to the wireless power transmission apparatus via the secondary core if a measured magnetic field value from the magnetic sensor is lower than a reference magnetic value and the communication with the wireless power transmission apparatus is available.

主权项

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 for detecting a foreign object; and a receiving controller to determine the foreign object is detected if the detected magnetic field value from the magnetic sensor is lower than a reference magnetic field value, to determine the foreign object is not detected if the detected magnetic field value is equal to or greater than the reference magnetic field value, and 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 the reference magnetic field value and communication with the wireless power transmission apparatus is available, wherein the error code represents the foreign object is detected, and wherein the wireless power signal is not received when the error code is not transmitted to the wireless power transmission apparatus because of the communication with the wireless power transmission apparatus is not available.
