Definitions

  • each battery powered device such as a wireless communication device such as a cell-phone requires its own charger and power source, which is usually the AC power outlet. This becomes unwieldy when many devices need charging.
  • Efficiency is of importance in a wireless power transfer system due to the losses occurring in the course of wireless transmission of power. Since wireless power transmission if often less efficient that wired transfer, efficiency is of an even bigger concern in a wireless power transfer environment. As a result, when attempting to provide power to one or more charging devices, there is a need for methods and apparatuses for communicating between a transmitter and a receiver to determine the power requirements of the receiver.

  • FIG. 1 illustrates wireless transmission or charging system 100 , in accordance with various exemplary embodiments of the present invention.
  • Input power 102 is provided to a transmitter 104 for generating a radiated field 106 for providing energy transfer.
  • a receiver 108 couples to the radiated field 106 and generates an output power 110 for storing or consumption by a device (not shown) coupled to the output power 110 .
  • Both the transmitter 104 and the receiver 108 are separated by a distance 112 .
  • transmitter 104 and receiver 108 are configured according to a mutual resonant relationship and when the resonant frequency of receiver 108 and the resonant frequency of transmitter 104 are exactly identical, transmission losses between the transmitter 104 and the receiver 108 are minimal when the receiver 108 is located in the “near-field” of the radiated field 106 .
  • Transmitter 104 further includes a transmit antenna 114 for providing a means for energy transmission and receiver 108 further includes a receive antenna 118 for providing a means for energy reception.
  • the transmit and receive antennas are sized according to applications and devices to be associated therewith. As stated, an efficient energy transfer occurs by coupling a large portion of the energy in the near-field of the transmitting antenna to a receiving antenna rather than propagating most of the energy in an electromagnetic wave to the far field. When in this near-field a coupling mode may be developed between the transmit antenna 114 and the receive antenna 118 . The area around the antennas 114 and 118 where this near-field coupling may occur is referred to herein as a coupling-mode region.
  • FIG. 2 shows a simplified schematic diagram of a wireless power transfer system.
  • the transmitter 104 includes an oscillator 122 , a power amplifier 124 and a filter and matching circuit 126 .
  • the oscillator is configured to generate at a desired frequency, which may be adjusted in response to adjustment signal 123 .
  • the oscillator signal may be amplified by the power amplifier 124 with an amplification amount responsive to control signal 125 .
  • the filter and matching circuit 126 may be included to filter out harmonics or other unwanted frequencies and match the impedance of the transmitter 104 to the transmit antenna 114 .
  • the receiver may include a matching circuit 132 and a rectifier and switching circuit to generate a DC power output to charge a battery 136 as shown in FIG. 2 or power a device coupled to the receiver (not shown).
  • the matching circuit 132 may be included to match the impedance of the receiver 108 to the receive antenna 118 .
  • antennas used in exemplary embodiments may be configured as a “loop” antenna 150 , which may also be referred to herein as a “magnetic” antenna.
  • Loop antennas may be configured to include an air core or a physical core such as a ferrite core. Air core loop antennas may be more tolerable to extraneous physical devices placed in the vicinity of the core. Furthermore, an air core loop antenna allows the placement of other components within the core area. In addition, an air core loop may more readily enable placement of the receive antenna 118 ( FIG. 2 ) within a plane of the transmit antenna 114 ( FIG. 2 ) where the coupled-mode region of the transmit antenna 114 ( FIG. 2 ) may be more powerful.
  • the resonant frequency of the loop or magnetic antennas is based on the inductance and capacitance.
  • Inductance in a loop antenna is generally simply the inductance created by the loop, whereas, capacitance is generally added to the loop antenna's inductance to create a resonant structure at a desired resonant frequency.
  • capacitor 152 and capacitor 154 may be added to the antenna to create a resonant circuit that generates resonant signal 156 . Accordingly, for larger diameter loop antennas, the size of capacitance needed to induce resonance decreases as the diameter or inductance of the loop increases. Furthermore, as the diameter of the loop or magnetic antenna increases, the efficient energy transfer area of the near-field increases.
  • resonant circuits are possible.
  • a capacitor may be placed in parallel between the two terminals of the loop antenna.
  • the resonant signal 156 may be an input to the loop antenna 150 .
  • Exemplary embodiments of the invention include coupling power between two antennas that are in the near-fields of each other.
  • the near-field is an area around the antenna in which electromagnetic fields exist but may not propagate or radiate away from the antenna. They are typically confined to a volume that is near the physical volume of the antenna.
  • magnetic type antennas such as single and multi-turn loop antennas are used for both transmit (Tx) and receive (Rx) antenna systems since magnetic near-field amplitudes tend to be higher for magnetic type antennas in comparison to the electric near-fields of an electric-type antenna (e.g., a small dipole). This allows for potentially higher coupling between the pair.
  • “electric” antennas e.g., dipoles and monopoles
  • a combination of magnetic and electric antennas is also contemplated.
  • the Tx antenna can be operated at a frequency that is low enough and with an antenna size that is large enough to achieve good coupling (e.g., > ⁇ 4 dB) to a small Rx antenna at significantly larger distances than allowed by far field and inductive approaches mentioned earlier. If the Tx antenna is sized correctly, high coupling levels (e.g., ⁇ 2 to ⁇ 4 dB) can be achieved when the Rx antenna on a host device is placed within a coupling-mode region (i.e., in the near-field) of the driven Tx loop antenna.
  • a coupling-mode region i.e., in the near-field
  • FIG. 4 shows simulation results indicating coupling strength between transmit and receive antennas.
  • Curves 170 and 172 indicate a measure of acceptance of power by the transmit and receive antennas, respectively. In other words, with a large negative number there is a very close impedance match and most of the power is accepted and, as a result, radiated by the transmit antenna. Conversely, a small negative number indicates that much of the power is reflected back from the antenna because there is not a close impedance match at the given frequency.
  • the transmit antenna and the receive antenna are tuned to have a resonant frequency of about 13.56 MHz.
  • Curve 170 illustrates the amount of power transmitted from the transmit antenna at various frequencies. Thus, at points 1 a and 3 a, corresponding to about 13.528 MHz and 13.593 MHz, much of the power is reflected and not transmitted out of the transmit antenna. However, at point 2 a, corresponding to about 13.56 MHz, it can be seen that a large amount of the power is accepted and transmitted out of the antenna.
  • curve 172 illustrates the amount of power received by the receive antenna at various frequencies.
  • points 1 b and 3 b corresponding to about 13.528 MHz and 13.593 MHz, much of the power is reflected and not conveyed through the receive antenna and into the receiver.
  • point 2 b corresponding to about 13.56 MHz, it can be seen that a large amount of the power is accepted by the receive antenna and conveyed into the receiver.
  • Curve 174 indicates the amount of power received at the receiver after being sent from the transmitter through the transmit antenna, received through the receive antenna and conveyed to the receiver.

  • a device is removed from the coupling-mode region.
  • This “removed” state may be that the device is physically removed from the coupling-mode region, the device is shut off, or the device cloaks itself, perhaps because it does not need any more power.
  • the transmitter periodically sends out a DQ for all the devices in the coupling-mode region. If two consecutive DQs to a specific device do not return a valid DS, the transmitter removes the device from its list of allocated devices and reallocates the power period 450 ′ to the remaining devices. The transmitter will also assign the missing device a power allocation of zero time in case it is still receiving by is unable to transmit. If a device was erroneously removed from the power allocation, it may regain power allocation by responding to and NDQ with a proper NDR.
  • Table 3 illustrates a non-limiting sequence of commands and replies to illustrate how the communication protocol operates.
  • the first slot assignment for the new device allocates no time slot.
  • Each existing device is allocated a new non-overlapping time slot, then the new device is finally allocated a time slot for receiving power.
  • a wireless charging devices may display a visible signal, such as, for example, a light to the user indicating that it has successfully entered the charging region and registered itself to the local transmitter. This will give the user positive feedback that a device is indeed prepared to charge.
  • the receiver and transmitter may comm
  • the receiver and transmitter may communicate on a separate communication channel 119 (e.g., Bluetooth, zigbee, cellular, etc) as is shown in FIG. 2 .
  • a separate communication channel With a separate communication channel, the recurring period need not include any communication periods and the entire time may be devoted to the power period 450 ′.
  • the transmitter may still allocate time slots to each receive device (communicated over the separate communication channel) and each receive device only gets on the bus for its allocated power segment Pdn.
  • time-multiplexed power allocations described above may be the most-efficient method for supplying power to multiple receive devices within a transmitter's coupling-mode region.
  • other power allocation scenarios may be employed with other embodiments of the present invention.
  • FIGS. 16A-16D are simplified block diagrams illustrating a beacon power mode for transmitting power between a transmitter and a one or more receivers.
  • FIG. 16A illustrates a transmitter 520 having a low power “beacon” signal 525 when there are no receive devices in the beacon coupling-mode region 510 .
  • the beacon signal 525 may be, as a non-limiting example, such as in the range of ⁇ 10 to ⁇ 20 mW RF. This signal may be adequate to provide initial power to a device to be charged when it is placed in the coupling-mode region.
  • FIG. 16B illustrates a receive device 530 placed within the beacon coupling-mode region 510 of the transmitter 520 transmitting the beacon signal 525 . If the receive device 530 is on and develops a coupling with the transmitter it will generate a reverse link coupling 535 , which is really just the receiver accepting power from the beacon signal 525 . This additional power, may be sensed by the load sensing circuit 216 ( FIG. 12 ) of the transmitter. As a result, the transmitter may go into a high power mode.
  • FIG. 16C illustrates the transmitter 520 generating a high power signal 525 ′ resulting in a high power coupling-mode region 510 ′.
  • the receive device 530 is accepting power and, as a result, generating the reverse link coupling 535 , the transmitter will remain in the high power state. While only one receive device 530 is illustrated, multiple receive devices 530 may be present in the coupling-mode region 5 10 . If there are multiple receive device 530 they will share the amount of power transmitted by the transmitter based on how well each receive device 530 is coupled. For example, the coupling efficiency may be different for each receive device 530 depending on where the device is placed within the coupling-mode region 510 as was explained above with reference to FIGS. 8 and 9 .
  • FIG. 16D illustrates the transmitter 520 generating the beacon signal 525 even when a receive device 530 is in the beacon coupling-mode region 510 . This state may occur when the receive device 530 is shut off, or the device cloaks itself, perhaps because it does not need any more power.
  • the receiver and transmitter may communicate on a separate communication channel (e.g., Bluetooth, zigbee, etc).
  • a separate communication channel the transmitter may determine when to switch between beacon mode and high power mode, or create multiple power levels, based on the number of receive devices in the coupling-mode region 510 and their respective power requirements.
