Abstract: 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.

Abstract: 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.

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).
