Abstract
A pick-up circuit for an inductive power transfer (IPT) system includes a series-tuned pick-up coil and a plurality of parallel AC processing circuits provided between the series-tuned pick-up coil and an output, each processing circuit being adapted to produce an output signal based directly or indirectly at least in part on a voltage of the series-tuned pick-up coil and including a switch for selectively coupling the processing circuit to the output so as to selectively provide the respective output signal to the output of the pick-up circuit.
