摘　　要：将三电平逆变器与异步电动机有机相结合,建立了高效简洁的逆变器—异步电动机数学模型。通过此模型,用Matlab/Simulink软件对三电平逆变器的空间矢量控制方法进行了仿真。仿真结果证实了控制方法的有效性和模型的正确性,为三电平逆变器的研究提供了一个有效的工具。A simple and effective mathematic model of threelevel inverter and induction machine is built by analyzing the inverter and induction machine as a whole. Using this model, a space voltage vector (SVV) control method for threelevel NPC voltage source inverters is simulated by the Matlab/Simulink software. The simulation results verify the validity of this control method and the mathematic model. Thus, an effective tool is provided for the research of threelevel inverters.
