Abstract
Coupled inductor systems are disclosed in which transmitter and receiver inductors, or coils, are coupled in a configuration for wirelessly transferring power and/or data among them. In preferred implementations, the systems are used for transmitting both power and data in pairs of coupled coils. Primary side circuits in preferred embodiments of the systems of the invention employ Class D or Class G amplifiers.
