摘要

针对储能式多流制机车在蓄电池牵引模式时复用牵引变流器主电路这种方式可能导致蓄电池对地电压超过额定绝缘电压而引起蓄电池损坏问题，详细介绍了主电路的结构和控制原理，重点分析了蓄电池对地电压，得出了蓄电池斩波升压后的中间电压与蓄电池对地电压的关系。通过MATLAB/Simulink进行了仿真验证，仿真结果与分析计算结果一致。

Abstract

Aiming at the problem of reusing the main circuit of traction converter in battery traction mode of energy storage multi-current locomotive, which may lead to the voltage of battery to ground exceeding the rated insulation voltage and cause battery damage, the structure and control principle of the main circuit were introduced in detail, the voltage of battery to ground was analysised emphasisly, and the relationship of battery to ground voltage and middle DC voltage after boosting was obtained. Through MATLAB / Simulink, the simulation results were consistent with the analysis and calculation results.
