Abstract :
Autonomous underwater vehicle (AUV) has become a main tool for underwater exploration and research. The mission capability of AUV is often limited by its on-board energy source, and it is usually the most limiting factor on activity of AUVs. The way of recharging AUVs costs a lot of time at present. In this paper, we propose a scheme to recharge AUVs wirelessly underwater. The scheme can not only omit the tedious work of changing battery, but also let the charging process more convenient and rapid. In this paper, we give the structure of AUV recharging system and topology of inductive coupling circuit. By analyzing the impedance model of load, we get the relation between transmission efficiency and parameters of circuit components. To prove the theoretical analysis, we build the simulation model of single load and multiple loads. From the results of simulation, we can see in the condition of multiple loads that the voltage of output is 24V in single load. When the second load is working at 0.05s, the voltages of two loads are equal to 15V. In the condition of multiple loads, the system can supply power to loads equally and stably.
