Abstract:
1. An inductive power outlet operable to transfer power to an inductive power receiver, said inductive power outlet comprising: a platform for supporting said inductive power receiver; at least one primary inductive coil embedded in said platform; an alignment mechanism configured to facilitate alignment between said primary inductive outlet and said inductive power receiver such that an inductive couple is formed between said primary inductive coil and a secondary inductive coil of said inductive power receiver, said inductive couple having a characteristic resonant frequency; and a driving circuit wired to said primary inductive coil, said driving circuit comprising a switching unit configured and operable to provide an oscillating driving voltage across said primary inductive coil such that a secondary voltage is induced in the secondary inductive coil; wherein said driving circuit is configured and operable to produce said oscillating driving voltage at a transmission frequency substantially different from said characteristic resonant frequency of said inductive couple.
