Abstract Inductive links establish two-way communication between the transmitter and receivers to transmit contactless energy. In wireless power and data transfer systems, the transmission of information and control signals contribute to the progress of technical and operational parameters. We have worked on the frequency multiplex analysis, and the results are presented in this work. Using a lab-based system, the output results... Read More
