摘要
蓄电池用双向DC/DC变换器(BDC)的关键部分是实现对系统能量流动的判断和控制。在此,基于变换器阻抗给出了一种能量判断模型及控制策略,分析了电流限幅值对系统稳定性的影响,并推导出选取电流限幅值的准则。给出了系统数学方程,并搭建了实验平台,实验结果验证了模型的可行性和理论分析的正确性。
The key part of bidirectional DC/DC converter（BDC） in battery needs to judge and control the flow of system energy.The molding of energy flow estimation and control strategy are proposed based on the impedance of converter.Relationship between current limit and system stability is analyzed and criterion about the selection of current limit is derived.Finally, the digital equation of sysytem is given and a 12 kW experimental platform is designed.Experimental results demonstrate the feasibility of model and the correction of theoretical analysis.
