摘　　要：针对3000马力节能环保型调车机车牵引供电系统要求,设计了三电平DC/DC双向变换器,介绍了主电路拓扑及工作原理,对Buck与Boost模式的控制策略进行了仿真与试验验证。结果表明,研究的三电平DC/DC双向变换器既可对牵引直流母线供电,也可对动力电池进行充电,可实现电能的双向传递,其性能满足设计要求。For the traction power supply system of 3000 horsepower energy-saving shunting locomotive,a three-level DC/DC bidirectional converter was designed,the topology and working principle of the main circuit were introduced,and the control strategies of Buck and Boost modes were simulated and tested.The results show that the three-level DC/DC bidirectional converter studied in this paper can not only supply power to the traction DC bus,but also charge the power battery,which can realize the bidirectional transmission of electric energy and meet the design requirements.
