摘要：
In order to improve the output power and the output stability in the magnetically-coupled resonant wireless power transfer (MCR-WPT) system, we analyzed the equivalent circuit of MCR-WPT topology of LCL-S type by use of mutual inductance model. From the point of view of system design, the method of parameter configuration was studied. The formula of output power and transmission efficiency was obtained, and the parameter setting method was put forward. The parameters about the LCL-S type MCR-WPT system used for low power electrical equipment was obtained. The system in which the frequency is 124 kHz and the distance between the emitting coil and the receiving coil is 12 cm was designed. Aiming at the dynamics of the load and the uncertainty of the relative position between a emitting coil and a receiving coil in practice, we investigated the effects on the transmission characteristics of the design system by simulation analysis and test design. The analysis and the test show that the output power and the stability of the wireless power transmission system can be improved with reasonable parameter configuration of the LCL-S type MCR-WPT system. The output stability can be increased by 4%. © 2019, High Voltage Engineering Editorial Department of CEPRI. All right reserved.
