基于DDQ线圈的双耦合LCL拓扑IPT系统及其抗偏移方法研究
|
摘要
基于传统LCL补偿拓扑IPT电路,该文将LCL拓扑中用于补偿的电感替换为一对耦合线圈,既可保证电路谐振,线圈间互感又为系统提供了一个新的能量传输通道,即一种双耦合LCL拓扑IPT系统。首先介绍了DDQ线圈结构与双耦合LCL拓扑电路的特点;理论结果表明,与传统单耦合LCL拓扑IPT系统的传输效率相比,所提出的双耦合LCL系统效率提升了0.8%。此外,该文还提出了一种将LCL拓扑切换为SS补偿拓扑的方法,有效提高系统在偏移时的功率输出能力。最后,通过实验验证了该系统的有效性与抗偏移能力:正对时两对耦合线圈传输功率分别为233W和392W,效率达95.5%;在偏移0～17cm范围内,输出功率始终高于500W,传输效率始终高于88.7%。
A dual coupled LCL(DCLCL) based IPT system was proposed in this paper by replacing the resonant inductor with a pair of coupled coils on the basis of traditional LCL topology IPT system for the purpose of keeping circuit resonant and providing another power transmission channel.Firstly, the characteristics of DDQ coil's structure and DCLCL circuit were analyzed. In addition, the efficiency of the system is 0.8% higher than that of the traditional single coupled LCL(SCLCL) based IPT system. Besides, a method of switching compensation topologies from LCL to SS was proposed to improve output power against misalignment. The anti-misalignment performance of the proposed IPT system were verified by experiments showing that the transmission powers of the two coupled coils are 230 W and 395 W respectively at 95.5% system efficiency. The output power is always greater than 500 W with the efficiency higher than88.7% when the coil misalignment ranges from 0 to 17 cm.
