Simultaneous inductive power and data transmission system for smart applications
Inductive power transfer (IPT) development is a big issue amongst the scientific community but there are only few solutions for communication between the primary and secondary side. This article presents a completely contactless near field system, which can provide power and data simultaneously using one common inductive power link. In this novel approach both transmission channels are designed collaboratively to maximize their performance. Based on these joint system specifications, the requirements for each system are derived, analyzed, simulated and measured. From this measurement the performance of the system is classified. To verify the joint specifications, the mutual interferences are evaluated and the system is compared to the state of the art.
