| Abstract: | The paper expounds principles of magnetically coupled resonant wireless power transfer(MCR-WPT). By equivalent model establishment and transfer efficiency equation conclusion through analysis, the influencing factors of system transfer efficiency such as load impedance, system frequency, coil diameter, radius, coil turns, position and transfer distance are obtained. The effect of influencing factors on efficiency from the theoretical analysis is simulated and verified to provide a reference for efficiency improvement of magnetically coupled resonant wireless power transfer system. |
