Abstract

The power supply of underwater equipment adopts a wireless power supply system that is easy to convert constant voltage and constant current, which can improve the safety of the system. The T-type CLC-S structure wireless power supply system studied in this paper has the characteristics of constant voltage and constant current output, and it is easy to switch the working mode by adjusting the working frequency, without changing the circuit structure or component parameters. In this paper, the conditions for the T-type CLC-S wireless power transmission system to realize the constant current and constant voltage output mode, the transmission power and transmission efficiency in the constant voltage and constant current mode are deduced, the selection of the working point is analyzed, and the transmission characteristics of the system are verified by simulation and experiments, so that the ZPA operation of the inverter can be realized regardless of constant voltage or constant current.
