| Abstract: | The optimization of transmission efficiency for a magnetic coupling resonant-wireless power transfer(MCR-WPT) system with a relay resonator is discussed. Based on the construction and analysis of an equivalent circuit model with relay coils, the power transmission performance parameter |Sij|2 is introduced, and the closed form solution of the optimal coupling coefficient between the transmitting coil and the relay receiving coil is derived when the positions of the relay receiving coil and terminal receiving coil are fixed. On this basis, the optimal distance between the transmitting coil and the relay receiving coil is determined to maximize the total system transmission efficiency. Through the coil design and related experiments, the consistency between the analysis and experimental results was verified. Results show that the MCR-WPT system can easily configure the optimal coupling coefficient to maximize the power transmission efficiency, providing an important reference for the efficiency optimization of the WPT system with a relay resonator. |
