超级电容有轨电车充电装置系统研究

摘要

在超级电容有轨电车充电系统中,单相Buck电路结构因存在功率等级低、输出纹波较大、变换器转换效率低等缺陷无法满足设计要求,为此提出四相交错并联的拓扑结构,并对其关键部件的作用一一进行了阐述,给出了充电装置输出电感的设计方法,在Matlab/Simulink环境中搭建了成套充电装置的系统仿真模型,仿真和实验验证了该系统的有效性和正确性,该系统已成功应用于实际工程中.%Due to the low power level,high output ripple,low conversion efficiency and other defects,single phase Buck circuit structure can not meet the design requirements of the charging system for the super capacitor tramcar.Therefore,a topology of four phases interleaved is presented,the roles of its key parts are illuminated and the output inductance of the charging device is designed.The simulation model of the system is set up in the Matlab/Simulink environment.The validity and correctness of the system are verified by both the simulation and the experiment.The system has been successfully applied to the practical engineering.
