  • 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). A foreign object detector (219) detects a presence of a foreign object in response to a comparison of the measurement spatial distribution to a reference spatial distribution.

  • 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: 20200212725
    Abstract: A power transmitter (101) for a wireless power transfer system comprises a transmitter coil (103) and a driver (201) generates a drive signal for the transmitter coil (103) employing a repeating time frame with a power transfer time interval and a foreign object detection time interval. A test generator (211) generates a test drive signal for a test coil (209) during the foreign object detection time interval. A foreign object detector (207) performs a foreign object detection test based on a measured parameter for the test drive signal. Prior to entering a power transfer phase, an adapter (213) controls the power transmitter (101) to operate in a foreign object detection initialization mode in which a preferred value of a signal parameter for the test drive signal is determined in response to at least a first message received from the power receiver (105). During the foreign object detection time interval the signal parameter of is set to the preferred value.

  • 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: 10615646
    Abstract: A wireless power transfer system includes a power transmitter (101) arranged to provide a power transfer to a power receiver (105) via a wireless inductive power signal. A parasitic power loss detector (207) is arranged to detect a parasitic power loss for the power transfer, and a user indicator (209) is arranged to initialize a user alert in response to the detection of the parasitic power loss. The system comprises an input (211) for receiving user inputs; and a controller (213) which is arranged to initiate an adaptation of a parasitic power loss detection operation performed by the parasitic power loss detector (207) to detect parasitic power losses if a user input meeting a criterion is not received. Each of the individual features may be implemented in the power transmitter (101), the power receiver (105), or may e.g. be distributed between these. The approach may allow improved foreign object detection in a wireless power transfer system.

  • Patent number: 10523052
    Abstract: A wireless power transfer system includes a power receiver and a power transmitter providing power using an inductive power signal. The power transmitter includes a resonance circuit having capacitive and inductive impedances, and a driver configured to generate a drive signal for the resonance circuit. A frequency modification circuit is configured to control the resonance frequency of the resonance circuit by slowing a state change for the capacitive and/or inductive impedance for a fractional time interval of at least some cycles of the drive signal, The frequency modification circuit is configured to align at least one of a start time and an end time for the fractional time interval to transitions of a timing signal. In the power transmitter, the driver is configured to generate the timing signal to have transitions synchronized to the drive signal. The slowing may be by impeding current flow between the capacitive and inductive impedances.

  • 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.

  • Patent number: 10193393
    Abstract: A wireless power transfer system includes a power receiver and a power transmitter providing power to this using an inductive power signal. The power transmitter comprises a variable resonance circuit (201) having a variable resonance frequency and generating the inductive power signal. A driver (203) generates the drive signal and a load modulation receiver (303) demodulates load modulation of the inductive power signal. An adaptor (305) adapts the operating frequency and the resonance frequency to converge, and specifically is arranged to control the operating frequency and the resonance frequency to be substantially the same. The adaptation of the operating frequency and the resonance frequency is further in response to a demodulation quality measure. The invention may allow improved communication, and in particular may reduce intermodulation distortion.
