A wireless charging receiver, system, and control method, and relates to the field of wireless charging technologies are disclosed. A receiver coil of the receiver converts an alternating magnetic field transmitted by a transmitter to an alternating current, and delivers the alternating current to a compensation network. The compensation network compensates the alternating current, and then delivers the compensated alternating current to a rectifier. The rectifier rectifies the compensated alternating current to a direct current, and supplies the direct current to a load. The compensation network is a compensation circuit with a current source characteristic, so that the receiver coil and the compensation network, acting together with the transmitter, make an input end of the rectifier a constant current source.
