  • Publication number: 20210036556
    Abstract: The present disclosure provides an apparatus and method for detecting a foreign object in a wireless power transmitting system. The wireless power transmitting apparatus measures an initial transmission power transmitted from the primary core block and performs foreign object detection on the basis of the initial transmission power, once it is found that an initial voltage of an output terminal of the wireless power receiving apparatus connected to an external load is within the range of a reference voltage. By performing foreign object detection while a wireless power receiving apparatus is in an initial setting completion state, before the output of the wireless power receiving apparatus is turned on, delay in detecting foreign objects may be reduced, and a risk due to heating of a foreign object may be avoided.

  • Patent number: 10886780
    Abstract: A non-contact power transmission apparatus accurately determines the kind of object that is placed on the charging deck of the non-contact power transmission apparatus, and, only when a non-contact power receiving apparatus is placed on the power transmission apparatus, allows power transmission and data communication to take place, thereby accurately determining the state of the receiver side and efficiently controlling the transmission of power. In the power transmission apparatus, the power supplied to the non-contact power receiving apparatus is measured, and the output power of the wireless power signal output from two different cores is controlled, thereby allowing the charging operation to be stably conducted even if the non-contact power receiving apparatus is moved anywhere on the power transmission apparatus.
