摘要： Exemplary embodiments are directed to wireless power transfer including generating an electromagnetic field at a resonant frequency of a transmitter to create a coupling-mode region within a near field of the transmitter during a synchronization portion of a time-multiplexed recurring period. During a power transmission portion of the recurring period, the electromagnetic field will continue to be generated when there is a receiver within the coupling-mode region, or the electromagnetic field will be disabled when there are no receivers within the coupling-mode region. Different segments of the power transmission portion are allocated to different receivers. The transmitter issues serial commands to the receivers by on/off keying the electromagnetic field. The receivers issue serial replies by changing the amount of power consumed from the electromagnetic field between two different states. The serial commands and serial replies are used to determine the number of receivers, their power requirements, and the allocation of segments.

摘要： Exemplary embodiments are directed to wireless power transfer including generating an electromagnetic field at a resonant frequency of a transmit antenna to create a coupling-mode region within a near-field of the transmit antenna. A receive antenna placed within the coupling-mode region resonates at or near the resonant frequency. The receive antenna extracts energy from a coupling between the two antennas. Signaling from the receive antenna to the transmit antenna is performed by generating a first power consumption state for the receive antenna to signal a first receive signal state and generating a second power consumption state for the receive antenna to signal a second receive signal state. Signaling from the transmit antenna to the receive antenna is performed by enabling the resonant frequency on the transmit antenna to signal a first transmit signal state and disabling the resonant frequency on the transmit antenna to signal a second transmit signal state.

摘要： Exemplary embodiments are directed to wireless power transfer including generating an electromagnetic field at a resonant frequency of a transmit antenna to create a coupling-mode region within a near field of the transmit antenna. A receive antenna placed within the coupling-mode region resonates at or near the resonant frequency. The receive antenna extracts energy from a coupling between the two antennas. A load sensing circuit coupled to an amplifier driving the transmit antenna can detect a change in power consumed by the amplifier in response to the energy extracted by the receive antenna. The transmit antenna adjusts to a high-power charging mode when one or more receivers are present in the coupling-mode region and adjusts to a low-power beacon mode when there are no receivers in the coupling-mode region.

摘要： This disclosure provides systems, methods and apparatus for increasing the efficiency of an amplifier when driven by a variable load. In one aspect a transmitter device is provided. The transmitter device includes a driver circuit characterized by an efficiency. The driver circuit is electrically connected to a transmit circuit characterized by an impedance. The transmitter device further includes a filter circuit electrically connected to the driver circuit and configured to modify the impedance to maintain the efficiency of the driver circuit at a level that is within 20% of a maximum efficiency of the driver circuit. The impedance is characterized by a complex impedance value that is within a range defined by a real first impedance value and a second real impedance value. A ratio of the first real impedance value to the second real impedance value is at least two to one.
