Patent abstract
A device and circuits are provided for wireless power transfer (WPT) gate-drive power reduction. A WPT receiver circuit includes a receive coil to couple to a transmit coil of a WPT transmitter circuit. A rectification circuit is coupled to the receive coil to generate a rectified voltage. The rectification circuit is a bridge rectifier circuit including a first set of field-effect transistors (FETs). One or more gate-drive control circuits improve power dissipation of the rectification circuit by controlling drive voltages of gate terminals of the first set of FET switches after start-up of the WPT receiver circuit.
