At present, the Wireless Power Transmission(WPT) system has a certain research and application foundation, and there are application cases in both high voltage and low voltage research fields. There are also application cases in both high-frequency transmission technology and low-frequency transmission technology. However, the Wireless Power Transmission(WPT) systems studied at present are relatively complex, and all those involved in the field of Wireless Power Transmission(WPT) need strong algorithm and system technical support, which makes it difficult to carry out follow-up research. The main reasons for this situation are as follows: 1. There are few key reference data; 2. The difference between high voltage technology and low voltage technology is obvious, and the technical integration between the two is difficult; 3. The difference between using high frequency transmission and using low frequency transmission is also large. The problems that need to be considered by the system become complex with the increase of transmission frequency. Starting from the zero point and the hardware design of the transmission system, this paper first designs the system hardware that can work stably, and realizes the physical production of the hardware and ensures the stable work. Secondly, the control algorithm is selected, and a lot of experimental data are obtained under the overall debugging experiment of the system. Finally, the experimental data are analyzed. Finally, the optimal choice should be made under various conditions and the optimal system configuration will be obtained.The paper is divided into five parts, and the corresponding contents of each part are as follows: (1) The first chapter introduces the problems and research background of this paper. First of all, the Wireless Power Transmission(WPT) system is briefly introduced.
