Abstract： Wirelesspower transfer （WPT） technology provides an effective solution for near-shore energy transmission in ships.This paper proposes a design method fora high-power，high-effciency WPT system based on the LCC-S compensation topology. The loss characteristics of the WPT system are analyzed，folowed by a detailed examination of the relationship between system efficiency and primary inductance. Optimal effciency point parametersare determined，and a magnetic integrated coupling mechanismis designed to enhance transmission performance.Circuit simulations are conducted to validate the theoretical analysis.Furthermore，an experimental platform isestablished，and the experimental results confirm the efctivenessof the proposed method.The system achieves an output power of and an overall efficiency of 96% ，demonstrating the feasibility and superior performance of the proposed design approach.
