英文摘要： Becaouse of its more merits,such as Energy Saving, environmental, higher efficient, the research and popularize of electric vehicle is urgent for more countries. While the battery is the bottleneck to develop electric vehicle for more years. With the development of wireless power transfer ,it may be the shortcut for resolving that puzzle of electric vehicle. We want to research in depth the theory and method of wireless high power supply for moving device in middle range. Three key problems are needed to solve emphatically: Research on the adaptive impedance match networks, method for decreasing the device size and increasing its power transmission distance, robustness controlling for resonance frequency. The characteristic or innovation is: the new concepts of wireless power supply to electric vehicle is proposed, the the method and control strategy for adaptive impedance match is proposed to solving wireless high power transfer for moving device, the new concepts and method of FTFME is proposed to solving resonance frequency obustness . Not only the puzzle of power source in electric vehicle can be resolved but also the meaning of wireless power transfer can be enriched with that achievement, which has more theory meaning and practical value.
