摘　　要：引入一种超级电容器电压均衡控制策略的模型,在此基础上提出一种新颖的超级电容器电压均衡方法——开关分流电压均衡法,该方法可以直接改变每个超级电容器的能量流动,实现能量重新分配。阐述了该方法的均衡原理及均压过程,给出了参数整定原则,同时基于PSIM仿真软件,对三只串联超级电容器模块进行仿真分析并与多飞渡电容电压均衡法进行对比,结果表明:开关分流电压均衡法均压速度快,效率高,在大容量快速储能领域中具有一定的价值。A model for ultra-capacitor voltage balancing strategy was introduced, and on this basis, a novel ultra-capacitor voltage balancing method was proposed, namely switching shunt voltage balancing method, which can directly change the energy flow of each ultra-capacitor to achieve the purpose of energy redistribution. The working principle and process of the proposed method were analyzed, and the parameter tuning principles were given. The simulation analysis and experiment of the module composed of three ultra-capacitors connected in series were performed based on PSIM, and was compared with multi flying-capacitive voltage equalizing method. The results show that the switching shunt voltage balancing method is fast, efficient, reliable and possesses high value for ultra-capacitor fast large capacity energy storage.
