Due to the threshold voltage of diode switches, existing symmetrical voltage equalizers suffer from voltage drops across battery cells. To overcome this problem, this letter presents a novel voltage equalizer for series‐connected batteries. The proposed inductor‐less cross‐coupled topology allows the voltage of each battery cell to be balanced evenly without a threshold voltage drop, because no diode switch is required to design the proposed voltage equalizer. The effectiveness of the proposed voltage equalizer is confirmed through experiments. © 2020 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

具有交叉耦合结构的电感器无电压均衡器

由于二极管开关的阈值电压，现有的对称电压均衡器遭受电池单元两端的电压降的困扰。为了克服这个问题，这封信提出了一种用于串联电池的新型电压均衡器。拟议的无电感器交叉耦合拓扑结构可在没有阈值压降的情况下均匀地平衡每个电池单元的电压，因为不需要二极管开关来设计拟议的电压均衡器。通过实验证实了所提出的电压均衡器的有效性。©2020日本电气工程师学会。由Wiley Periodicals LLC发布。
