本文重新构造了一种串并联开关电容器（SC）功率变换器，作为串联电池或超级电容器的一种新型电压均衡电路。推导了新型电压均衡器的模型，并成功地用于分析均衡速度和能量损失。它是分析和设计基于sc的均衡系统以满足不同平衡速度要求的一个非常有用的工具。该分析和建模方法可推广到其他基于sc的电压平衡系统。建立了样机并给出了实验结果，验证了理论分析和建模方法。
A series-parallel switched-capacitor (SC) power converter is reconfigured as a new voltage equalization circuitry for series-connected batteries or supercapacitors in this paper. The model of the new voltage equalizer is derived and successfully used to analyze the equalization speed and the energy loss. It is a very useful tool to analyze and design the SC-based equalization systems to meet different balancing speed requirements. The analysis and modeling methods can be extended to other SC-based voltage-balancing systems. A prototype is built and the experimental results are provided to confirm the theoretical analysis and the modeling method.
