Summary:This paper discusses the implementation of a system that utilizes inductive coupling and single-conductor techniques in order to enable power and data transmission through a metallic structure. The power and data transfer occur simultaneously over the same structure. The source of power is connected to a double-ended coil that is coupled with a single-ended resonator through a resonant inductive coupling mechanism. This second coil is attached to the single conductor responsible to transfer power to another device. At the receiver side of the system, a similar couple of coils is used to transmit energy to the receiver device. The system operates according to the Qi standard for wireless power transfer, working at the frequency of 300 kHz. These characteristics ensure the portability, reliability, and interoperability of the system. A model is developed for the proposed system. The system is implemented over several arbitrary metallic structures and different combinations of coils and resonators. The measured power efficiency as high as 75% is achieved. The adaptive matching technique is proposed to maintain the performance of the system over a variety of operating conditions.
