Title: (EN) Apparatus and method for detecting foreign object in wireless power transmitting system
(ZH) 无线电力传输系统的异物检测装置及方法
Abstract: front page image
(EN) An apparatus and method for detecting a foreign object in a wireless power transmitting system are provided. In a case in which a foreign object is not detected prior to charging, an attempt to detect a foreign object detection during charging is performed, and when a foreign object is not detected while a power signal is being received, power is limited based on a temperature sensor.
