Abstract
A self-adaptive protection circuit and method for double-voltage startup of a wireless charging system are provided. The method controls a double-voltage logic control module of a double-voltage starting circuit to send a signal for exiting a double-voltage mode by detecting an input voltage of a receiving terminal of the wireless charging system. By the input voltage of the receiving terminal of the wireless charging system, the double-voltage logic control module of the double-voltage starting circuit is controlled to send the signal for exiting the double-voltage mode, thus protecting the receiving terminal of the wireless charging system from the over-high input voltage in the double-voltage mode.
