摘要： 为解决电动汽车采用静态无线充电方式时充电频繁、续航里程短的问题，设计了电动 汽车移动式无线供电系统，并建模仿真。首先设计了一种多逆变器并联的逆变电路，以满足 供电系统对大功率的需求；其次采用双边 LCC 补偿拓扑，并对其进行 T 变换后完成计算分析。 最 后 设 计 了 双 初 级绕组 并 联 的 无 线 供 电 系 统 和 单 初 级 绕 组 无 线 供 电 系 统 ， 使 用 MATLAB/Simulink 完成模型搭建和仿真。仿真分析表明，与单初级绕组无线供电系统相比， 双初级绕组并联的无线供电系统具有更高的传输功率和效率。

Abstract: In order to solve the problem of frequent charging and short cruising range when electric vehicles adopt the static wireless charging method, a mobile wireless power supply system for electric vehicles is designed and modeled and simulated. Firstly, an inverter circuit with multiple inverters in parallel is designed to meet the high power demand of the power supply system. Secondly, a bilateral LCC compensation topology is adopted, and the calculation and analysis are completed after T-transformation. Finally, a wireless power supply system with two primary windings in parallel and a single primary winding wireless power supply system are designed, and the model building and simulation are completed using MATLAB/Simulink. Simulation analysis shows that, compared with the wireless power supply system with single primary winding, the wireless power supply system with two primary windings in parallel has higher transmission power and efficiency.
