EMU train traction system key Circuit Analysis andSimulation
Abstract ：AC drive traction power for the Chinese railway development is an importantdirection, the paper three-level EMU traction converter and single-phase four-quadrant inverterbasic principles to analyze, and gives single-phase four-quadrant converter transient currentcontrol method and SPWM method, on this basis, while the three-level SPWM converterconducted in-depth research. Next, in order to make the single-phase three-level rectifiersimulation model simulation model three converter system, I use Matlab / Simulink simulation.While the three-level inverter SVPWM simulation models to do a detailed simulation study,and obtained simulation results.This article is based on the kinetic theory EMU three-level converter systems researchup mathematical models. We are mainly mathematical modeling and the establishment of asingle-phase three-phase three-level inverter three-level rectifier critical systems simulationmodeling. Create a mathematical model to study three-level topology to lay the foundation. Inthis paper, the above were analyzed in detail, especially in three basic principles of EMUtraction converter for single-phase four-quadrant converter transient current control method andSPWM method is given, and a three-level principle of SPWM rectifier are analyzed in detail.Finally, we use MATLAB / SIMULINK simulation capabilities modeled three-level converter.For single-phase three-level rectifier simulation, three-level inverter SVPWM were simulated,and get the final result, and determine the reliability of the method.
Keywords: EMU； three-level converter; single-phase three-level rectifier; simulation
