提出了一种基于输入-串联-输出-串联（ISOS）电路的超级电容储能双功能变换器模块。与现有的拓扑结构相比，所提出的电路既作为超级电容器单元电压均衡器，又作为输出电压调节器。在充电过程中，串联反激式转换器通过旁路将能量从充满电的电池传输到电池组。因此，完全充电的电池保持额定端电压，其余电池的充电速度增加。在放电过程中，模块的输出电压可以用同一组变换器调节。分析了充放电过程的工作原理。介绍了反激变换器及其控制系统的设计。实现了一个由三个子模块组成的原型系统。实验结果验证了该拓扑结构的有效性。© 2016日本电气工程师协会。由John Wiley & Sons公司出版
A bifunctional converter module for supercapacitor energy storage based on an input‐series‐output‐series (ISOS) circuit is proposed in this paper. Compared to the existing topologies, the proposed circuit acts both as a supercapacitor cell voltage equalizer and as an output voltage regulator. During the charging process, series‐ connected flyback converters transfer energy from fully charged cells to the string via a bypass. Therefore, the fully charged cells maintain the rated terminal voltage, and the charging speed of the rest of the cells increases. During the discharging process, the output voltage of the module can be regulated with the same set of converters. The working principles during the discharging/charging processes are analyzed. The designs of the flyback converter and the control system are presented. A prototype consisting of three submodules is implemented. Experimental results verify the effectiveness of the proposed topology. © 2016 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
