摘　　要：针对海流扰动及水下航行器定位精确度有限的问题,提出了一种适用于基站和水下航行器之间进行电能传输的电磁耦合器—环型铁氧体磁芯式电磁耦合器。应用有限元方法分析系统的磁场分布,计算间隙变化下电磁耦合器漏感和励磁电感。建立了含有补偿电容的电磁耦合器等效电路,进一步分析海流扰动下系统的电压增益和效率。应用理论模型对电磁耦合器性能进行分析,分析结果表明,环形电磁耦合器具有稳定的电压增益及效率。制作微缩模型进行试验,试验结果表明,该耦合器适用于水下航行器的非接触式电能传输。A type of electromagnetic coupler which named annular cerrite electromagnetic coupler is put forward for transmitting power to underwater unmanned vehicle from underwater dock.Finite element method was applied to analyze the magnetic field distribution of the system,and the leakage inductance and the magnetizing inductance were calculated and analyzed with different gap distances.Furthermore,equivalent circuit of the electromagnetic coupler with compensation capacitor was established to analyzed voltage gain and efficiency of the system,and the ocean current disturbance influence on voltage gain and efficiency was analyzed.The performance of the system was predicted by the theory model,and analysis results show that the annular electromagnetic coupler has the advantages of stable voltage gain and efficiency.A miniature of annular ferrite electromagnetic coupler was produced to test,and the results show that the electromagnetic coupler is particularly suitable for underwater non-contact power transmission.
