摘　　要：车载牵引变压器小型轻量化是机车高速运行的需要,在车载变压器小型轻量化上有几种相互竞争的方案,针对这些方案做了较系统的总结,并对它们的优缺点进行了比较分析,提出了使用直流斩波技术实现无变压器化交流传动系统的新方案。The miniaturization and lightening of on-board traction transformer is required for high-speed running of locomotive. Several schemes are listed for the miniaturization and lightening of on-board traction transformer. Systematic conclusions are done to these schemes and comparisons are made to their advantages and disadvantages. The new program is proposed to use DC chopper technology for the realization of AC drive system without transformer.
