Single-Contact Electrical Power Transmission on the Conductive Surface Using H-Bridge Inverter

In this paper, we developed a transceiver system to transmit and receive electrical power through a single wire without a physical ground or return path on the receiver side. We systematically develop and analyze the system through the High-Frequency Structure Simulator (HFSS) and develop a unified model for the transceiver. The developed system uses open-ended coils to efficiently transmit and receive electrical power through a single wire. All high-speed silicon switches are used in developing the system at an operating frequency of ∼1 MHz. An output power of 10 W is measured at the load side with a total conversion efficiency of more than 50%, which is significantly higher than the earlier published work in the MHz range. A complete design methodology for the transceiver module is also proposed.
