Abstract
In the wireless charging receive apparatus of the electronic device, a first communication circuit receives charging data, where the charging data is used to indicate a charging type. A first controller identifies, based on the charging data, that the charging type is a first charging type, and outputs a first rectifier control signal to control a first rectifier circuit to operate in a half-bridge mode. Alternatively, a first controller identifies, based on the charging data, that the charging type is a second charging type, and outputs a second rectifier control signal to control a first rectifier circuit to operate in a full-bridge mode. A first receive coil receives an alternating magnetic field and outputs a first induced voltage.
