英文摘要： There are some deficiencies for the traditional two coils or four coils magnetic coupling resonant wireless power transfer system, such as short transmission distance and incapability of area-covering charging. In order to overcome these shortcomings, the mathematic model and the applications of the wireless power transfer networks (WPTN) constructed by multi-sources and multi-repeaters to cover multi-loads in certain regions is studied in the research. The main contents in the research are listed as the following. (1) Establishing and simplifying the mathematic model of the WPTN consisted of multi-loads, multi-sources and multi-repeaters. (2) The sensitive and dependence of the transmission efficiency, load pick-up power and transferred distance to the parameters such as the resonance frequency, the inductive coupling coefficients, inductances of the coils, the compensation capacitances, the numbers and the positions of the sources, loads and repeaters is studied to explore the mathematical regularities within them and the compensation technologies. (3) Researching the interaction between the WPTN and the electromagnetic mediums over the surrounding environment and exploring the novel frameworks of WPTN covering certain regions and their designing criteria. (4) The control theory of dynamic adjusting WPTN due to the variations of the external charging circumstances. Therefore, this project is of important theoretical significance for the study on the mathematical model and practical significance for the design, planning and optimization of WPTN.
