Research on Underwater Wireless Power and Information Synchronous Transmission Technology

With the continuous development of underwater unmanned vehicles, they have taken on important underwater tasks, and the requirements for their power and information transmission capabilities have been increasing. The underwater wireless power and information synchronous transmission technology can not only deliver energy, but also transmit information. This paper analyzes and designs a wireless power and information synchronous transmission system. Energy and information are transmitted through different coupling coils, and the coupling coils are analyzed through simulation. Furthermore, the inverter circuit is designed. The field programmable gate array (FPGA) is used to generate square wave signals to drive the inverter to achieve DC to AC conversion and generate modulated signals for information transmission. The correctness of the program is verified. Based on these, the design of the whole underwater wireless power and information synchronous transmission system can be further developed.
