This application provides a wireless charging receive end, system, and control method, and relates to the field of wireless charging technologies. The wireless charging receive end includes a receiver coil, a compensation network, a power converter, and a receive end controller. The receiver coil converts an alternating magnetic field transmitted by a transmit end into an alternating current and transmits the alternating current to the compensation network. The compensation network compensates for the alternating current and then transmit a compensated alternating current to the power converter. The power converter rectifies the compensated alternating current into a direct current for charging a load. The receive end controller obtains a reference signal at the transmit end based on an input current of the power converter and an input reference current, and sends the reference signal at the transmit end to a transmit end controller, so that the transmit end controller controls the transmit end based on the reference signal at the transmit end. Because the receive end controls the input current of the power converter at the receive end, the input current of the power converter at the receive end can be prevented from overcurrent, to protect the power converter at the receive end, and improve reliability of the wireless charging system.
