摘　　要：本文研究了一种采用CUK变换器拓扑结构实现相邻两串联电池间能量转移的非隔离型分布式变换器均衡电压法。文章介绍了均压电路的工作原理,进行了理论分析,同时采用电压反馈和电流反馈双闭环控制的均衡方案,在MATLAB/Simulink中建立了该均压电路的仿真模型,给出了仿真结果和实验结果。结果验证了该种方法的可行性。This paper explored a distributed non-isolated converter equalizing method based on CUK converter topology structure to realize the energy exchange between two series-connected batteries. The working principle of the equalizing circuit was introduced, and the theoretical analysis was carried on. In the meantime, by using a balanced scheme of double closed-loop control with voltage feedback and current feedback, the simulation model of the equalizing circuit is established in MATLAB/Simulink. The simulation results and experimental results demonstrated the feasibility of this approach.
