Abstract: A power transmitter and/or receiver for a wireless power transfer system comprises a power transfer coil (103, 107) arranged to exchange power via a power transfer signal. A receiver (207, 307) is arranged to receive first data from the complementary power transfer apparatus. The first data is modulated onto the power transfer signal in accordance with a first modulation scheme where each data symbol is represented by a sequence of time intervals each having a constant modulation level dependent on a data symbol value for the data symbol. A transmitter (205, 305) is arranged to transmit second data to the complementary power transfer apparatus by modulating the power transfer signal in accordance with a second modulation scheme. The symbol duration for data symbols of the second modulation scheme are a divisor of a duration of at least one time interval of the sequence of time intervals. A synchronizer (209, 309) is further arranged to synchronize the transmitter (205, 305) to transmit the second data aligned with the first data by synchronizing the transmission of the second data to the power transfer signal.

Abstract: A power transmitter (101) provides power to a power receiver (105) via an electromagnetic power transfer signal. The power transmitter (101) comprises an output circuit (302, 103) with a transmitter coil (103) generating the power transfer signal in response to a drive signal generated by a driver (301). A configuration controller (303) switches between power transfer configurations having different maximum power limits and voltage amplitudes for the drive signal. A transmitter (307) transmits a power configuration message to the power receiver (105) comprising data indicative of a voltage amplitude for a first power transfer configuration a receiver (305) receives a power transfer configuration change request message from the power receiver (105). The configuration controller (303) switches the power transmitter (101) to the first power transfer configuration in response to the power transfer configuration change request message. The approach allows a power transmitter and receiver to collaborate to change power transfer configurations providing different maximum power limits.

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.

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.

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.

Abstract: A wireless power transfer system comprises a power transmitter (101) arranged to generate a wireless inductive power transfer signal for powering a power receiver (105). The system comprises a temperature controlled power loop setting an operating temperature for a heating part of a powered device. The system further comprises a receiver (207) for receiving a first temperature for a part of a powered device where the powered device is powered by the power receiver (105). A comparator (209) compares the measured temperature to a first reference temperature associated with the power transmitter (101). In response to the first temperature exceeding the reference temperature, a controller (213) proceeds to restrict the power of the power transfer signal and/or to generate a user alert. The first temperature may specifically relate to a contact surface of the powered device and the reference temperature may be a maximum allowable temperature of a contact surface for receiving the powered device during power transfer.

Abstract: A power transmitter (101) comprises a transmitter coil (103) for generating the power transfer signal during a power transfer phase. A driver (201) generates a drive signal for the transmitter coil (103) to generate the power transfer signal during the power transfer phase. A communicator (205) receives messages from the power receiver (105) and a controller (203) is arranged to, during the power transfer phase, generate a reduced power time interval during which a power level of the power transfer signal is reduced where the reduced power time interval is generated in response to the communicator (205) receiving a reduced power time interval request message from the power receiver (105). The power receiver (105) may generate a request message when e.g. a change in operating mode occurs. The power receiver (105) may ensure that a request message, and thus a reduced power time interval, is only generated when the power receiver can handle a power interruption for the power transfer signal.
