Abstract:
 A type of electromagnetic coupler which named annular ferrite 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.
