摘　　要：为了提高水下航行器的充电便捷性,水下无线充电系统得到发展,但同时水下无线充电技术仍然存在充电传输效率较低、传输功率较低的问题。而充电传输效率和功率与补偿网络的选取和耦合器的形状、参数等相关,因此实现对补偿网络和耦合器的优化对于无线充电系统传输效率和功率的提升有重要意义。首先,对磁感应耦合式无线充电电路中补偿网络选用原边串联-副边并联补偿方式,对传输功率、效率进行理论推导和分析。其次,对耦合器的尺寸结构进行仿真建模,得到参数符合的耦合器。在此基础上,建立水下无线充电仿真系统进行仿真,得到仿真参数。最后,进行器件选取和驱动电路、原副边电路PCB板的设计制作,进而搭建了一台无线充电系统样机平台进行实验,并得到实验结论。In order to improve the charging convenience of underwater vehicles,the underwater wireless charging system is developed,but at the same time the underwater wireless charging technology still has the problems of low charging transmission efficiency and low transmission power.The charging transmission efficiency and transmission power are related to the selection of the compensation network and the shape and parameters of the coupler,so it is important to realize the optimization of the compensation network and coupler for the improvement of the transmission efficiency and power of the wireless charging system.Firstly,the primary-side series-parallel compensation method was selected for the compensation network in the magnetic induction coupled wireless charging circuit,and the theoretical derivation and analysis of the transmission power and efficiency were carried out.Secondly,the dimensional structure of the coupler is simulated and modeled to obtain a coupler with conforming parameters.Based on this,the underwater wireless charging simulation system was established,simulated,and the simulation parameters were obtained.Finally,the device selection and the design and fabrication of the driver circuit and the primary and secondary circuit PCB boards were carried out.Then,a prototype platform of the wireless charging system was built,experiments were conducted and experimental conclusions were obtained.
