Abstract

See full text

A rectification and regulation circuit for a wireless power receiver includes a coil for magnetically coupling to a primary coil of a power transmitter, a full-wave rectifier circuit separate from the power transmitter and a control unit separate from the power transmitter. The full-wave rectifier has a first pair of controllable rectifiers including a first transistor connected to a first terminal of the coil and a second transistor connected to a second terminal of the coil. The control unit is operable to control switching of the transistors of the full-wave rectifier so that the full-wave rectifier (a) generates a rectified output for charging a battery of the wireless power receiver by rectifying current through the coil or voltage across the coil, and (b) regulates the rectified output.
