摘要：
A new I-type guideway for electric vehicle wireless power transfer system is designed to improve recharging mileage and shorten charging time, considering road conditions, adaptability of working conditions, high efficiency of energy conversion and reliability. The coupler and its electromagnetic shielding structure are designed and optimized with simulation, and the stability and anti-offset ability of power wireless transmission are analyzed. The ferrite structure of the coupler is optimized to improve its transmission efficiency. Besides, the structure of high frequency power conversion and road construction are analyzed and designed. A 100-meter dynamic wireless charging test road section in Zhangbei County is constructed to evaluate system function, performance and electromagnetic safety. At rated power 20kW and driving speed 40km/h, average efficiency of the system reaches 76%, verifying engineering feasibility of the structure designed in this paper. © 2019, Power System Technology Press.
