Abstract:
1. A contactless power supply for providing power to a remote device through an inductive coupling, said contactless power supply located on the primary side of said inductive coupling and said remote device located on a secondary side of said inductive coupling, said contactless power supply comprising: a resonant circuit located on said primary side of said inductive coupling, said resonant circuit having a primary for transferring power to said remote device located on said secondary side of said inductive coupling; a receiver located on said primary side of said inductive coupling, said receiver for receiving information from said remote device located on said secondary side of said inductive coupling, wherein said receiver receives said information independently of said inductive coupling; a circuit sensor located on said primary side of said inductive coupling, said circuit sensor operatively coupled to said resonant circuit located on said primary side of said inductive coupling, said circuit sensor generating a sensor output indicative of a characteristic of power being affected by a characteristic of said remote device located on said secondary side of said inductive coupling, wherein said characteristic of said remote device is reflected through said inductive coupling; and a controller located on said primary side of said inductive coupling, said controller coupled to said receiver and said circuit sensor wherein said controller is programmed to control operation of said contactless power supply in response to said sensor output and said information from said remote device received by said receiver.
