摘要： A return communication system and method for an Inductive Power Transfer (IPT) System allows a pick-up device (3) to receive an instruction and supply a load (36) in such a way that a predetermined variation occurs in current in the primary conductive path (2) of the system The variation may be detected and decoded to determine a response from the pick-up to the instruction.
