基于海水环境下ICPT系统电磁耦合器的研究

摘要

Inductively coupled power transmission technology (ICPT) is the recent rise of a new type of power transmission mode. In view of the influence of current turbulence on ICPT system transmission performance in the deep sea, ANSYS finite element simulation software is used to analyze the changing trend of coupling coefficient and inductance parameters in different gaps of the electromagnetic coupler with the eccentricity. Mutual inductance equivalent circuit with compensation capacitor is designed to calculate and analyze influencing factors of system power and transmission efficiency under resonance conditions. Simulation study is also made for the changing rule in which system power and transmission efficiency vary with input voltage, load resistance, frequency and turns per coil so as to provide reference for the optimization design of ICPT transmission system in the marine conditions.%感应耦合电能传输技术（ICPT）是近来兴起的一种新型电能传输模式。针对深海环境下海流扰动影响ICPT系统传输性能稳定的问题，利用ANSYS有限元仿真软件分析电磁耦合器不同间隙下耦合系数和电感参数随磁芯偏心量的变化趋势。建立含有补偿电容的互感等效电路，计算分析系统谐振情况下系统功率和传输效率的影响因素，仿真研究系统功率和传输效率随输入电压、负载电阻、频率和线圈匝数的变化规律，为提高海水环境下ICPT输系统的优化设计提供参考。
