VI. CONCLUSIONS A dynamic wireless charging system with short segmented transmitting coils for inspection robot is proposed in this paper. This research mainly focuses on the issue of receiving power drop in the system with single energized mode when the receiving coil moves to the central position between two transmitting coils and proposes the switching control mode of double energized transmitting coils. In this paper, the uniform circuit model for the systems with single energized mode and the double energized mode are developed. The parameters of the compensation circuit are designed for the two systems. The comparative characteristics of the receiving power and the efficiency of the systems with single and double energized mode varying with the position of the receiving coil are investigated. The receiving power of the system with the proposed double energized mode is relatively stable during the process of the position changing of the receiving coil, especially when the receiving coil moves to the central position between two transmitting coils ACKNOWLEDGMENT This work was supported in part by National key R & D project (NO.2018YFB0106300), in part by the State Grid Corporation Science and Technology Project "Selection of Wireless Charging Frequency for Electric Vehicles and Its Impact on the Environment", in part by the National Nature Science Youth Foundation of China (51507032), in part by the Nature Science Youth Foundation of Jiangsu Province (BK20150617), in part by the Scientific Research Foundation of Graduate School of Southeast University (YBJJ1728), in part by the Postgraduate Research & Practice Innovation Program of Jiangsu Province (KYCX17-0088), in part by the Fundamental Research Funds for the Central University (2242016k30021), and in part by the China Scholarship Council.

N2 - In a dynamic wireless charging system with short segmented transmitting coils, the operation mode of a single energized transmitting coil causes large power drop when the receiving coil moves to the central position between two transmitting coils. Power stabilization based on double energized transmitting coils is proposed to solve this issue. Firstly, the dynamic wireless charging system for inspection robots based on series short segmented transmitting coils and LCC compensation circuit in transmitting side is presented. Secondly, the uniform circuit model of wireless power transfer systems with single transmitting coil or double transmitting coils is developed. The system characteristics of a single energized transmitting coil and double energized transmitting coils varying with the position of the receiving coil are analyzed comparatively in one cycle of switching control of the segmented transmitting coils. According to the comparative analysis, when the receiving coil is at the central position between the two transmitting coils, the receiving power is stabilized by using the double energized transmitting coil structure. The relevant experiments are designed to verify the theoretical research.
