| 摘 要： | 电压不均衡是制约超级电容串联应用的重要因素。文章对现有的超级电容电压均衡方法进行了简要讨论,提出了一种带隔离变压器的Cuk变换器动态均衡方法,并给出了相应的控制策略。利用PSIM软件对其均压性能和效果进行了仿真分析。仿真结果表明该动态均压电路均衡速度快、均衡性能好,对由于不同因素造成的电压不均衡都具有良好的均压效果。

| Abstract: | Voltage imbalance of super-capacitors is one of main factors restricting its series application. In this paper, the existing super-capacitors voltage balancing methods are briefly discussed and a dynamic equilibrium method based on Cuk converter with isolated transformer is put forward. The corresponding control strategy is presented. The result of simulation using PSIM shows that the speed and performance of dynamic equalizing circuit is perfect, furthermore, the proposed voltage balancing circuit have good equalizing performance to the imbalance caused by different kinds of factors. |
