摘要
本文以CRH2型高速动车组多电平牵引变流器为研究对象,将单相四象限变流器的瞬间电流控制策略和PWM控制方法相结合,提出了三电平逆变器空间矢量脉宽调制控制策略。通过Matlab/Simulink仿真平台来研究三电平牵引变流器在不同操作条件下的稳定性能,旨在验证该控制策略的正确性。
Based onthe CRH2 EMU group multilevel traction converter as the research object,single phase four quadrant converter instantaneous current control strategy and the control method of PWM combined,three level inverter space vector pulse width modulation control strategy is proposed. Through the Matlab/Simulink simulation platform to study the stability of the three level traction converter under different operating conditions,the purpose is to verify the correctness of the control strategy.
