本文介绍了一种谐振开关电容变换器（RSCC）的电压平衡的几个电容或电池串联连接的模块。该电压平衡电路利用软开关操作在电容器模块之间转移电荷，从而减少功率损耗和EMI。此外，相移控制方法能够改善其电压调节性能。它的电流回路分析的电路配置，其中有三个以上的电容器模块。在此基础上，设计了一种新的控制器来改善系统的瞬态响应。实验结果验证了所提出的控制方法的正确性和有效性。
This paper describes a resonant switched-capacitor converter (RSCC) for voltage balancing of several capacitor or battery modules connected in series. This voltage balancing circuit transfers electric charge between the capacitor modules with a soft switching operation, resulting in a reduction of power loss and EMI. Moreover, a phase-shift control method enables to improve its voltage-regulation performance. Its current loops are analyzed in a circuit configuration which has more than three capacitor modules. Based on the analysis, a new controller is designed to improve the transient response. Experimental results confirm the validity and effectiveness of the proposed control method.
