Integrated bidirectional converter with voltage equalizer for energy storage system

In energy storage systems, a voltage equalizer is always needed. The equalizers often include DC-DC converter. this paper, the converter in saved by integrating equalization circuit into bidirectional of battery system, thus simplifying system. integrated system composed LC resonant and multiplier, which has advantages simplicity low complexity. This paper presents design process based on analysis model, enables to obtain optimal parameter configuration. Test results show proposed LC-SVM can automatically realize balance between cells without additional control.
