Abstract
Coupled inductor signal transfer systems are disclosed in which transmitter and receiver coils are inductively coupled in a configuration for wirelessly transferring power and/or data signals. In preferred implementations, the systems may be used for transmitting both power and data. Preferred embodiments of the invention have at least one multi-tap coil on the primary side and/or secondary side of the system. The selection of taps enables the effective size and/or number of coils to be dynamically changed according to operational needs.
