摘要
针对新型有轨电车充电装置DC/DC变换器采用并联结构拓扑时两回路输出电流相差较大的问题,提出将自动均流控制技术应用到该装置中。给出了装置拓扑结构,详细分析了其工作原理;推导了系统状态方程,根据实际需求设计了仿真及实验参数。仿真及实验结果表明,采用自主均流控制技术的充电装置,能够很好地均衡两回路的输出电流。
The automatic master current sharing control technology is used in the charging-device with two circuits for the new tram, because of the difference of the two output currents is larger when DC/DC converter with parallel topology.The topology of the device is given and the working principle is analyzed in details.The state equation of the system is deduced,the parameters for the simulation and experiment on the basis of actual demand are listed.Simulation and experiment results show that the charging device with automatic master current sharing control could balance the output currents of the two circuits very well.
