A wireless charging receiving apparatus is provided, which includes a receiver coil, a rectifier, and a controller. The receiver coil is configured to receive electromagnetic energy and output an alternating current. The rectifier includes at least two controllable switches, and is configured to rectify the alternating current from the receiver coil to a direct current s. The controller is configured to perform phase-locking on a phase of a current fundamental component of the alternating current received by the rectifier, to obtain a periodic signal having a same frequency as the current fundamental component; and the controller is further configured to: generate a synchronization reference signal having the same frequency as the periodic signal, generate drive signals of the controllable switches in the rectifier based on the synchronization reference signal, and control, based on the drive signals, controllable switches in the rectifier to convert the alternating current into the direct current.
