Abstract: A wireless power receiver includes a power receiving circuit wirelessly receiving power transmitted from a wireless power transmitter so as to generate an induced current, and a rectifying-and-modulating circuit including first to eighth switches and a control unit. The control unit is operable to control operation of each of the first to eighth switches between conduction and non-conduction. Accordingly, the first to fourth switches cooperatively constitute a full-bridge rectifier for rectifying the induced current generated by the power receiving circuit, and each of the fifth to eighth switches is operable to switch synchronously with a respective one of the first to fourth switches or to became non-conducting, thereby changing an amplitude of the induced current.

Abstract: A power management unit, adapted to a wireless power supplying unit, for switching between input powers and providing a rated voltage or a variable flow current is provided. The power management unit includes a rectifying unit, a regulating unit, and a control unit. The rectifying unit converts AC power into DC power. The regulating unit is connected to the rectifying unit and generates a stable rated voltage or a variable flow current. The control unit is connected to the regulating unit and controls the input power driving the regulating unit. In addition, an apparatus and a method for a wireless power supplying unit are provided.
