Abstract
The performance of EMU traction converter is one of the most important factors for evaluating EMU’s operation safety and efficiency. This paper takes CRH1A and CRH2A EMU converters as research objects, and carries out research on two converters’performance analysis and optimization based on Matlab/Simulink software. This paper accords to actual design parameter of two converters’main circuits and builds up simulation models separately, then makes a comparison and analysis of the effects on system’s in-out performance imposed by main circuits’structures and their control methods. Based on this, this paper researches into SVPWM control method’s effect on improving converter in-out characteristics and dynamic performance applied to CRH2A EMU converter. The conclusion is preliminarily verified by simulation modeling. The results and data are basically consistent with expecting objectives.关键词
