  • Publication number: 20200343773
    Abstract: A wireless power transfer system includes a power transmitter (201) arranged to provide a power transfer to a power receiver (205) via a power transfer signal. The power receiver (205) comprises a first mode controller (709) for transmitting a standby mode exit request to the power transmitter (201) by changing a loading of a communication inductor (209) of the power transmitter (201). The power transmitter (201) comprises a mode controller (405) which controls the power transmitter (201) to operate in a standby mode wherein a presence of the power receiver (205) is detected but no power transfer signal is generated. It furthermore comprises a detector (403) for detecting an impedance change of the communication inductor (209). The mode controller (405) is arranged to initiate a transition from the standby mode to a power transfer mode in response to the detector (403) detecting the impedance change.

  • Publication number: 20200328616
    Abstract: A wireless power transfer system includes a power receiver (105) receiving a power transfer from a power transmitter (101) via a wireless inductive power transfer signal. The power transmitter (101) comprises a transmit power coil (103) generating the power transfer signal. A test signal coil (209) coupled to a test signal generator (211) generates a magnetic test signal. A plurality of spatially distributed detection coils (213) is coupled to measurement unit (215) generating a set of measurement values reflecting signals induced in the detection coils (213) by the magnetic test signal. A processor (217) determines a measurement spatial distribution of the measurement value where the spatial distribution reflects positions of the detection coils (213).

  • Patent number: 10778048
    Abstract: A wireless power transfer system includes a power transmitter (101) providing power to a power receiver (105) via an inductive power signal. The power transmitter (101) and receiver (105) can operate in different modes including a test mode and a power transfer mode. Operating parameters of the power receiver (105) are constrained in the test mode relative (and specifically the loading). A foreign object detector (209) generates a foreign object detection estimate from a comparison of a measured load to an expected load of the inductive power signal when the power receiver is operating in the test mode. A controller (211) enters the power transmitter (101) and receiver (103) into the power transfer mode when the foreign object detection estimate is indicative of no detection of a foreign object. In the power transfer mode, a parasitic power loss detector (207) generates a parasitic power loss detection for the power transfer if a parasitic power loss estimate is outside a range.

  • Publication number: 20200144869
    Abstract: A wireless power transfer system comprises at least one power receiver (105) for receiving a power transfer from the power transmitter (101) via a wireless inductive power transfer signal. Configurers (207, 306) of the power transmitter and receiver may perform a configuration process to determine a set of power transfer parameter values which are used in a first power transfer. The power transfer parameter values and a first identity for the first power receiver (105) are stored. After a detection of an absence of the power receiver by a first controller (211), a detector (213) may detect a presence of a candidate power receiver. If the candidate power receiver is detected within a given duration and has an identity matching the first identity, an initialization processor (215) initializes a second power transfer using the set of stored parameter values. Otherwise it discards the set of stored parameter values.

  • Patent number: 10536035
    Abstract: A wireless power transmitter (101)) comprises a resonance circuit (201) comprises a transmitter inductor (103) for generating a power transfer signal for wirelessly transferring power to the power receiver (105). A driver (203) generates a drive signal for the resonance circuit (201) and a resonance modification circuit (505) aligns the resonance frequency of the resonance circuit (201) with the drive frequency of the drive signal by slowing a state change for resonance circuit (201) for a fractional time interval of cycles of the drive signal. A load estimator (509) generates a load estimate reflecting an equivalent load resistor for the transmitter inductor (103) reflecting the loading of the power transfer signal. A drive frequency adapter (511) then adapts the drive frequency in response to the load estimate. The invention may in particular improve load modulation communication quality.

  • Patent number: 10396595
    Abstract: A method is presented of allocating communication time slots contained in repeating frames for communication between an inductive wireless power transmitter and at least two inductive wireless power receivers, wherein the power transmitter and the power receivers are arranged to communicate by means of modulation and demodulation of an inductive power signal. The transmitter sends synchronization messages marking the start of the communication time slots and the frames, and messages indicating if a time slot is unallocated. A receiver may send, during an unallocated time slot, send a message to the transmitter requesting allocation of the unallocated communication time slot. The transmitter subsequently sends messages to indicate if the communication was successfully received, and if the allocation request is granted.
