Abstract
A novel pulse synchronization scheme is proposed in this brief based on simultaneous wireless power and data transfer (SWPDT) technology to address the pulse synchronization issue of the undersea bidirectional wireless power transfer (BWPT) system due to the special characteristics of the undersea environment. Accurate pulse synchronization can be implemented by adapting the software to the existing SWPDT system based on the DDQ coil. Furthermore, this brief proposes a phase lock scheme that can eliminate the issue of pulse false triggering, which is caused by the interference of the BWPT channel to the data channel. A prototype with an output power of 1 kW and a data rate of 1 Mb/s demonstrates the feasibility of the pulse synchronization scheme proposed in this brief. The work of this brief extends the application of SWPDT technology and also presents a new solution for pulse synchronization in the BWPT system.
