Method and system of wireless power transfer foreign object detection |
摘要 |
A wireless power transfer foreign object detector having, at least one secondary receiver coil, an adjustable load electrically coupled to the at least one secondary receiver coil, and at least one temperature sensor providing at least one temperature detection signal, wherein the at least one temperature sensor is responsive to at least one thermal state of the at least one secondary receiver coil, and wherein foreign object detection is based at least in part upon the at least one temperature detection signal. |

1. A method of wireless power transfer foreign object detection comprising the steps of:
measuring at least one tuned temperature state of at least one secondary receiver coil; detuning an adjustable load of said at least one secondary receiver coil from at least one resonant frequency; measuring at least one detuned temperature state of said at least one secondary receiver coil; and determining at least one foreign object based at least in part upon said at least one tuned temperature state and said at least one detuned temperature state. |
