  • Wireless charging device and wireless charging switching method
    Patent number: 11750042
    Abstract: The present disclosure provides a wireless charging switching method, which includes steps as follows. After a proximity sensor disposed in the central area of a coil senses an object, it is determined whether a power bus voltage of a wireless power transceiver electrically connected to the coil has reached a predetermined voltage value during a predetermined period, so as to determine a receiver mode or a transmitter mode for the wireless power transceiver.
    Type: Grant
    Filed: April 8, 2021
    Date of Patent: September 5, 2023
    Assignee: MERRY ELECTRONICS (SHENZHEN) CO., LTD.
    Inventors: Ke-Yang Lai, Chih-Yung Wang, Huang-Wei Chen, Yung-Hsiang Liu
