Abstract:
Wireless energy transfer and bidirectional transfer of information and control signals, using the same inductive connection, has been a current topic of research in recent years. Depending on the required transmitted power and the speed of the transmitted information and control signals, several methods have emerged: a method with sequential transfer of energy and data, a method with simultaneous transfer of energy and data, using a change in the frequency of the inverter and the load resistance of the energy receiver, and a method of simultaneous energy and data transfer by frequency multiplexing. The focus of this paper is on the frequency multiplexing method. The paper analyzes energy transfer, bidirectional data transfer and a laboratory model has been developed to conduct experimental studies. Structural diagrams of program codes in the transmitter and receiver are presented, as well as the communication protocol used in the studies.
