Abstract
A wireless charging receive end, system, and control method related to the field of wireless charging technologies are provided. 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 based on an input current of the power converter and an input reference current, and sends the reference signal to a transmit end controller.
