Abstract

This paper starts with a mutual inductance coupling model and takes compensation structure of 'series connection-series connection' as an example to respectively deduce the mathematical expressions for system output power and efficiency when traditional resonant compensation strategy and non-resonant compensation strategy are adopted, so as to compare the advantages and disadvantages of the two strategies from the aspect of influence of coupling coefficient change on the output power and efficiency. Then, to cope with the drawbacks of non-resonant compensation strategy, a dynamic modelling method for electromobile's dynamic wireless charging system based on dual-LCL non-resonant compensation is proposed to analyse the structure's function of improving the system's power transmission capacity and determination method of different component parameters from the perspectives of circuit equivalence and impedance conversion. Models are built for rectifier and filter circuit, DC-DC circuit and loading battery pack for receiving terminal, and the characteristics of each link are expressed mathematically.

基于双LCL非谐振补偿的电动汽车动态无线充电系统动态建模方法

本文从互感耦合模型入手，以“串联-串联”补偿结构为例，分别推导出采用传统谐振补偿策略和非谐振补偿策略时系统输出功率和效率的数学表达式。从而从耦合系数变化对输出功率和效率的影响角度比较两种策略的优缺点。然后，针对非谐振补偿策略的不足，提出了一种基于双lcl非谐振补偿的电动汽车动态无线充电系统的动态建模方法，从电路等效和阻抗转换的角度分析了该结构对提高系统功率传输能力的作用以及不同组件参数的确定方法。建立了整流滤波电路、DC-DC电路和接收端负载电池组的模型，并对各环节的特性进行了数学表达。
