摘　　要：针对经典开关电容均压电路能量转移路径单一、均衡效率不高的问题,提出一种基于开关电容法的新型多回路均压电路。基于串联超级电容器组动态电路的零状态响应和非零状态响应进行电路分析,提出可用于多回路均压电路的均衡电容参数识别方法。通过试验表明,多回路均压电路及均衡电容参数识别方法可以显著提高串联超级电容器组的均压效果。A new multi-loop voltage equalization circuit based on the switched capacitor method was proposed to address the problems of single energy transfer path and low balancing efficiency in classic switched capacitor voltage equalization circuit.Based on the zero state response and non-zero state response of the dynamic circuit of the series supercapacitor group,circuit analysis was carried out to put forward a method for identifying the equalization capacitor parameter that can be used in multi-loop voltage equalization circuit.Through experiment,it is shown that the multi-loop voltage equalization circuit and equalization capacitor parameter identification method can significantly improve the voltage equalization effect of series supercapacitor group.
