摘要

双向无线电力传输技术(BD-WPT)可以实现电动汽车与电网之间的能量转换。随着无线电力传输实用化道路的发展和电动汽车市场保有量的不断增加，无线电力传输显示出广阔的前景。因此，本文提出了一种工作频率为85 kHz的双向3kw电动汽车无线电力传输系统的设计方法。采用相移控制和PI控制相结合的控制策略，提高了系统的性能。利用PLECS优化设计了G2V和V2G模式下基于LCC补偿网络的BD-WPT拓扑。仿真结果验证了所提电路结构和控制策略的正确性和可行性。

Research on Bidirectional Wireless Power Transfer System for Electric Vehicles

Bidirectional wireless power transfer(BD-WPT) can realize the energy conversion between electric vehicles(EVs) and the power grid. It has shown broad prospects because of the development of the practical road of wireless power transfer(WPT) and the increasing market holdings of EVs. Thus, the design methodology for a bidirectional 3 kW wireless power transfer system of electric vehicles, operating at frequency 85 kHz are proposed in this paper. And the control strategy combines phase shift control and PI control to improve system performance. Using PLECS the BD-WPT topology based on LCC compensation network is optimally designed for G2V and V2G modes. Simulation results has verified the correctness and feasibility of the proposed circuit structure and control strategy.
