摘要
基于磁耦合谐振式技术原理,采用一种双边LCC拓扑补偿网络参数设计方法。首先对双边LCC拓扑主电路数学模型进行分析,设定线圈自感与串联补偿电感的电感比值。然后通过编写M文件和搭建Simu⁃link仿真平台,根据电感比值与效率之间的关系,找到最优效率点。最后搭建全SiCMOSFET器件系统实验平台进行验证。实验结果表明,通过设置合适的电感比值,在满功率偏移范围内,耦合机构效率能够保持在95%左右,系统最大效率大于92.5%,证明了该补偿网络参数设计方法是有效的。
Based on the principle of magnetic coupling resonance technology,a bilateral LCC topology compensation network parameter design method was adopted.Firstly,the mathematical model of the main circuit of the bilateral LCC topology was analyzed,and the inductance ratio of the coil self-inductance and the series compensation inductance was set.Then,by writing an M file and building a Simulink simulation platform,according to the relationship between inductance ratio and efficiency,found the optimal efficiency point.Finally,a all-SiC MOSFET device system experimental platform was built for verification.The experimental results show that the efficiency of the coupling mechanism can be maintained at about 95%and the maximum efficiency of the system is more than 92.5%in the range of full power offset by setting the appropriate inductance ratio,which proves that the compensation network parameter design method is effective.
