Wireless power receiver

摘要

Exemplary embodiments are directed to conveying wireless power received at a receive antenna to a load. A method may include coupling each terminal of the antenna to a ground voltage during a charging phase for storing energy within the antenna. The method may further include coupling at least one terminal of the antenna to an output during an output phase for transferring energy from the antenna to the output.

1. A method for conveying energy from a wireless power receiver to a load, the method comprising:
during a charging phase for storing energy, actuating a first switching element to couple a first terminal of a receive antenna receiving wireless power to a reference voltage and actuating a second switching element to couple a second terminal of the receive antenna to the reference voltage, the receive antenna located in a coupling-mode region of a transmit antenna and receiving the wireless power from the transmit antenna while operatively coupled with the transmit antenna; and during an output phase for transferring the energy from the receive antenna to an output coupled to the load, actuating only one of the first switching element or the second switching element to decouple only one of the first terminal or the second terminal from the reference voltage.
