SYSTEM AND METHOD FOR CODED COMMUNICATION SIGNALS REGULATING INDUCTIVE POWER TRANSMISSION

摘要

An inductive power transfer system and method for transferring power to an electrical device wirelessly includes an inductive power outlet and an inductive power receiver. During operation, instruction signals are sent from the inductive power outlet to the inductive power receiver. When no instruction signals are transferred, the system is configured to deactivate such that power is drawn by the system only during operation.

1. A signal transmission circuit for an inductive power receiver, the signal transmission circuit operable to regulate inductive power transmission across an inductive power coupling, the inductive power coupling comprising at least one primary inductive coil associated with an inductive power outlet and a secondary inductive coil associated with the inductive power receiver,
the inductive power receiver comprising: the secondary inductive coil connectable to an electric load; the signal transmission circuit; and at least one electrical element selectively connectable to the secondary inductive coil by a switching unit; wherein: the signal transmission circuit is configured to generate at least one coded signal by connecting the electrical element to the secondary inductive coil in pulses having an identifiable characteristic frequency such that the coded signal is detectable by a signal reception circuit associated with the inductive power outlet.
