APPARATUS, SYSTEM, AND METHOD FOR DETECTING A FOREIGN OBJECT IN AN INDUCTIVE WIRELESS POWER TRANSFER SYSTEM BASED ON INPUT POWER |
摘要 |
An inductive wireless power transfer system comprises a transmitter configured to generate an electromagnetic field to a coupling region for providing energy transfer to a wireless power receiving apparatus. The transmitter includes control logic configured to determine a power component of the transmitter, and determine a presence of a foreign object within the coupling region in response to a comparison of the power component and a desired threshold for the power component. Related inductive methods for detecting a foreign object in an inductive wireless power transfer coupling region of an inductive wireless power transfer system and operating a sleep mode of a wireless power transmitter are disclosed.
