With the aim of sending electric power to autonomous underwater vehicles (AUVs), an automatic
wireless power supply system by means of electromagnetic coupler was proposed. An equivalent circuit of the
electromagnetic coupler with compensating capacitors was presented to analyze the performance of the system.
The magnetizing inductance and leakage inductance, which are important for choosing compensating capacitors,
were calculated by finite element analysis (FEA) methods. Then the voltage gain, power loss and system efficiency
were analyzed to optimize the winding turns. Finally, a phase-shift full bridge zero-voltage-switching converter
and an electromagnetic coupler were produced. The experimental results demonstrated that the proposed system
has a high voltage gain with small variation and sufficient power feeding.
