摘　　要：感应耦合电能传输（ICPT）可用于浮标系统水下传感器的长期稳定可靠供电。在此建立LCL补偿型浮标ICPT系统的模型,分析得出不同负载下,谐振点处该结构的输出功率和效率都较高;分析水下次级绕组LCL补偿与串联补偿的区别,当次级品质因数小于1时,LCL补偿输出功率更大;进而提出补偿电路的设计思路;建立LCL补偿型浮标ICPT系统实验平台。实验表明系统在12 V电源条件下,输出功率最高达到18.637 W,效率达到0.649,且能实现恒流输出,证明了设计的合理性,提升了系统性能。Inductively coupled power transmission（ ICPT） can be utilized for buoy underwater sensors power supply,which has the features stabilization and reliably in the long term. In this article,the LCL compensation model is formulated,and the resonance point of this model has higher output power and efficiency. By analyzing the difference between the LCL compensation and the series compensation in the underwater secondary side,the former has higher output power when the quality factor of the secondary side is less than 1. The design strategy of compensation circuit is proposed and the experimental platform of LCL compensation buoy ICPT system is built. The experiment results show that the output power and efficiency are 18. 637 W and 0. 649 under the condition of 12 V power supply,respectively. Meanwhile,the output current is constant. The correctness of the model is validated and the performance of the system is improved.
