Abstract: A bidirectional wireless power transfer system for transferring power comprises a power stage electrically connected to a transceiver element for an electric field and/or a magnetic field, and for extracting power from a generated electric field and/or a generated magnetic field. The power stage is for inverting an inputted power signal and for rectifying a received power signal. The system further comprises a trigger circuit for synchronizing wireless power transfer; and a clock generator for generating a clock signal. The system further comprises a switching element electrically connected to the power stage, and selectively electrically connected to the trigger circuit and the clock generator, such that: when the switching element electrically connects the clock generator to the power stage, the transceiver element is configured to transfer power by generating an electric field and/or a magnetic field, and when the switching element electrically connects the trigger circuit to the power stage, the transceiver element is configured to extract power from a generated electric field and/or a generated magnetic field.

Abstract: A rectifier for use in a receiver of a wireless power transfer system for receiving wireless power transferred for a transmitter of the wireless power transfer system. The rectifier comprises a field effect transistor (FET) comprising: a source terminal electrically connected to ground; a drain terminal electrically connected to a receive element of the receiver. The receive element is for extracting power from the transmitter of the wireless power transfer system. The FET further comprises a gate terminal electrically connected to the receive element. The gate terminal is driven by a gate signal in phase with an input signal received at the receive element.
