摘要： A power transmitter (501) transfers power to a power receiver (505) using a wireless inductive power signal between inductors of the devices. In the power transmitter (501) a power source (601) provides a power source signal which may have level variations. A power signal generator (603) generates a drive signal from the power source signal by means of a frequency converter (605) which increases the frequency of the drive signal relative to the power source signal. A limiter (607) for restricts the power of the drive signal fed to the inductor (503) to be below a threshold in repeating time intervals. A synchronizer (611) synchronizes the repeating time intervals to the power source signal. In the power receiver(505) a load coupler (1001) decouples the power load (1003) from the inductor (507) during the repeating time intervals and a synchronizer (1005) synchronizes the repeating time intervals of the receiver to the power signal. Communication units (609, 1007) exchange data during the repeating time intervals.

摘要： A power transmitter (101) comprises a driver (201) generating a drive signal for a transmitter coil to generate a power transfer signal during a power transfer time interval and an electromagnetic test signal during a foreign object detection time interval. A set of balanced detection coils (207, 209) comprise two detection coils arranged such that signals induced in the two detection coils by an electromagnetic field generated by the transmitter coil compensate each other. A first transformer (211) has a secondary winding and a primary winding coupled in series with the set of balanced detection coils. A foreign object detector (205) is coupled to the secondary winding and performs foreign object detection during the foreign object detection time interval. The foreign object detector (205) is arranged to detect a foreign object in response to a property of a signal from the first secondary winding meeting a foreign object detection criterion.

摘要： A power transmitter (101) is arranged to transfer power to a power receiver (105) via a wireless inductive power transfer signal transmitted from a transmit coil (103) to a power receiver (105). A first communication unit (305) communicates a message to the power receiver (105) on a first communication link A second communication unit (307) receives data from the power receiver (105) on a separate second communication link having a longer range. The power receiver (105) comprises a third communication unit (405) which receives the first message. A response generator (407) generates a response message to the message and a fourth communication unit (409) transmits the response message to the power transmitter (103) over the second communication link. The power transmitter (103) determines an expected response message to the message and a power controller (303) controls the power level of the power transfer signal dependent on whether a message is received on the second communication link corresponding to the expected response message.

摘要： 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.

摘要： A wireless power transfer system includes a power receiver and a power transmitter providing power using an inductive power signal. The power transmitter comprises a resonance circuit (201) comprising a capacitive impedance (503) and an inductive impedance (501). A driver (203) generates a drive signal for the resonance circuit. A frequency modification circuit (505) controls the resonance frequency of the resonance circuit (201) by slowing a state change for at least one of the capacitive impedance (503) and the inductive impedance (501) for a fractional time interval of at least some cycles of the drive signal. The frequency modification circuit (505) is arranged 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 (203) generates the timing signal to have transitions synchronized to the drive signal. The slowing may be by impeding current flow between the capacitive and inductive impedance (503, 501).
