摘　　要：为了保证浮标感应耦合电能传输(ICPT)系统在负载变化时仍然能够稳定工作,基于LCC拓扑电路,建立双LCC-S补偿型浮标ICPT系统模型,并提出一种实现水上初级线圈电流幅值恒定,负载端电压稳定输出的方法。首先分析了水下拾取端串联补偿的恒压特性,然后根据反射阻抗的特点,分析了系泊钢缆回路LCC拓扑、水上初级回路LCC拓扑的恒流特性。推导出了浮标ICPT系统各个回路补偿拓扑参数配置的约束条件,并据此设计了合理的ICPT系统参数来搭建样机进行实验,以验证理论分析的正确性。实验表明,系统在20 V电源时,水上发射线圈电流与接收端电压在负载变化时仍然能够保持稳定。In order to ensure that the inductively coupled power transfer(ICPT)system can still work stably when the load changes.Based on the LCC topology circuit,a model of ICPT system for double LCC-S compensatory buoy,and a method to realize constant current value and steady output of voltage at the load end of the water primary coil are proposed.Firstly,the constant pressure characteristics of series compensation for underwater pickup end are analyzed.Then,according to the resistivity of the reflection impedance,the constant current characteristics of the LCC topology of the steel cable loop and the LCC topology of the water loop are analyzed.The constraints of the configuration of the compensation topology parameters in each circuit of the buoy system are deduced.The constraints of the topology parameters of each loop compensation system of the buoy system are deduced,and the appropriate ICPT system parameters are designed to build the prototype to carry out experiments to verify the correctness of the theoretical analysis.Experiments show that when the system is powered by 20 V,the current of the water-emitting coil and the voltage of the receiving terminal can remain stable when the load changes.
