Abstract：This paper proposes a novel wireless power and data transmission (WPDT) system using double-sided LCC compensation topology. The power transmission circuit and the modulation, injection, extraction, and demodulation circuits for data transfer are analyzed. The function of each component in the system is explained in detail. The specific steps of system design are summarized. The mutual interference between power transfer and data transfer and the design rules to reduce the interference are discussed. A 100W WPDT prototype is built. The practically measured power transfer efficiency is 90.5%, and the data transmission rate is 119 kbit/s. Data transmission can work well even though the coupling coefficient is decreased by 60.2%. The practically measured interferences between power transfer and data transfer are quite small. The power transfer and data transfer are not affected by each other.
