Abstract
An inductive power pad (100) includes a plurality of transmitting inductors (120) and a respective plurality of detector circuits (140). Each transmitting inductor (120) is operable to provide inductive energy to a power receiver circuit (150). Each detector circuit (140) corresponds to one of the plurality of transmitting inductors (120) and each detector circuit (140) is operable to electromagnetically sense a power receiver circuit (150) in proximity thereto. Each detector circuit upon electromagnetically sensing a power receiver circuit, is further operable to control switching of its corresponding transmitting inductor to a power supply (130), thereby providing a supply voltage to said corresponding transmitting inductor, said supply voltage operable to generating inductive energy (110) for transmission to said power receiver circuit.
