摘要
针对城市轨道交通储能系统快速充电中出现的超级电容单体之间存在的电压不均衡问题,提出了一种非能耗型的快速均衡电路,介绍了均衡硬件电路的工作原理,分析了均衡器的均衡电流控制策略,并对4个串联超级电容组成的模组均衡电路进行了仿真和实验验证。
In this papper, in order to solve the voltage imbalance of series-connected super-capacitors in the fast charging urban rail transporta- tion system, a non-dissipative fast equalizer is proposed. The current equalization control strategy and hardware design are presented and equali- zation performance is verified by the simulation and experimental results of a charge equalizer prototype for four series-connected super- capacitors.
