摘要
串联超级电容器组的电容电压不平衡是阻碍超级电容器储能应用发展的一个重要因素,而实现串联超级电容器组的电压均衡可以延长其使用寿命、增加储存能量、提高储能系统的可靠性。讨论并比较了现存的各种均压方法,鉴于它们的不足之处,提出一种以逆变器转移超级电容能量的电压均衡方法,介绍了该方法的工作原理,并通过仿真和实验分析了它的优缺点。
The imbalance of voltage is a critical obstacle to the development of energy-storage system with series-connected uhracapacitors.Equalizing the voltage of series-connected uhracapacitors plays an important role in prolonging lives of ultracapacitors,increasing energy storage level, and enhancing the stability of the system.Different kinds of voltage-equalizing methods are discussed,and a new method of equalizing uhracapacitors'vohages using an inverter is proposed.Working principle of the voltage-equalizing system is introduced, and the advantages and disadvantages are analyzed through simulation and experimentation.
