摘　　要：电动汽车的发展对智慧城市的交通、环保、新型电力系统稳定等都具有重要的意义。本文基于无线充电和V2G的理念、提出一种LCC-S磁耦合补偿结构的二级式充电机。通过使用自适应虚拟同步机(virtual synchronous generator,VSG)控制,电动汽车既能实现双向无线充电,又能够起到调峰调频和惯量支撑的作用。本文详细分析了主电路原理和VSG控制策略,并通过仿真验证了控制的正确性和LCC-S无线充电拓扑维持母线电压稳定的优势。The development of electric vehicles(EV)has great significance for transportation,environmental protection,and the stability of new power systems in smart Smart cCities.This paper proposes a two-stage charger with LCC-S compensation structure based on the concept of wireless charging and V2G(vehicle to grid).By using the adaptive virtual synchronoussynchro generator(VSG)control,EV can not only achieve bidirectional wireless charging,but also play the role of peakand-frequency regulation and inertia support.In this paper,the main circuit principle and VSG control strategy are analyzed in detail,and the effects of different virtual inertia and damping coefficients on power regulation and frequency regulation are analyzed.Finally,the correctness of the control and the advantages of LCC-S wireless charging topology in maintaining bus voltage stability are verified by simulation.
