摘要
高频化是未来轨道交通车辆辅助变流系统轻量化、小型化必然的技术发展趋势,动车组与电力机车的辅助变流系统又具有高压大功率的特殊性。基于高频化实现方式及工程设计存在的局限性分析,提出三种可行的级联式动车组与电力机车高频辅助变流系统高频直流链主电路拓扑,分析了各自的特性与工作机理,并着重从成本、效率、体积、控制、均压特性、适应性等关键角度进行详细分析对比,结果显示三电平降压+串联谐振变换器拓扑的综合性能占优,最后通过整机建模仿真分析和功能样机试验验证该主电路的可行性及元件参数设计、系统控制策略的有效性。
Use of higher frequency is the inevitable technology development trend for light-weight and miniaturization for the auxiliary converter system of rail transit vehicles in the future.The auxiliary system of EMU and electric locomotive has the special characteristics of high voltage and high power.Based on engineering limitation and high-frequency implementation analysis,three available main circuit topologies of high-frequency auxiliary converter system for EMU or electric locomotive are proposed,and their characteristics and working mechanism are analyzed.Detailed analysis and comparison are carried out from the critical perspective of cost,efficiency,volume,control,voltage balance and adaptability, and the results show that the performance of TLBuck-LLC topology is the best.The feasibility of the main circuit topology and effectiveness of the parameter design and control strategy are verified by modeling simulation and functional prototype test.
