摘　　要：利用直流斩波技术实现高速机车无变压器化交流传动系统结构是实现车载牵引变压器小型轻量化的一种新方案,其需要解决的关键问题之一是直流斩波器电路元件参数的确定。通过建立斩波器的暂态方程,推导出稳态时状态方程的解,揭示出元件参数和斩波器稳态工作性能的关系。在这一基础上,确定出一组合理的元件参数。It is a new scheme for the miniaturization and tightening of the on-board traction wansformers that to achieve transformerless AC drive system by use of DC chopper. One critical problem to be solved is the determination of the parameters of the components for the DC chopper. The steady solution of the state equation for DC chopper is deduced by building the transient equation. The relation between the parameters of components and the steady performance of the chopper is illustrated. And the rational parameters are further set up.
