Power Regulation in Inductive Power Transfer via Power Line Communication

The use of Inductive Power Transfer (IPT) for feeding modern electronic systems and appliances is continuously increasing. As known, this technique allows energy transfer at relevant power levels (in the order of tens of kW) with distance between the transmitter and receiver coils of the order of tens of centimeters, and with efficiencies above 90%. In order to obtain these performances a form of synchronization between the primary and the secondary controller is often required. This paper examines the feasibility of the use of the inductive coupling for data transmission using the Power Line Communication (PLC) technique. Some preliminary results of the characterization of the transmission channel taken on a laboratory prototype are presented.
