Experimental studies of a method of simultaneous contactless transmission of energy and information signals through a common inductive link

Wireless power transfer and two-way transfer of information and control signals by using the same inductive link is a hot 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 been outlined: a sequential energy and data transfer method, a simultaneous energy and data transfer method, using a change of the frequency inverter and the load resistance, and a simultaneous power and data transfer via frequency multiplexing method. The main focus in the present work is dedicated to the frequency multiplexing method. A mockup was developed to demonstrate the effectiveness of the method and to perform experimental research.
