摘　　要：将单模式和双模式过调制技术分别应用于三电平SVPWM,使得调制范围扩大为0≤MI≤1;结合三电平的特点进行了过调制技术的分析和比较;最后在以一片TI TMS320LF2407A DSP为基础的二极管嵌位三电平开环V/F控制原理样机上进行了实验,结果表明了过调制技术在三电平中应用是可行和有效的。The single mode and two mode overmodulation technologies are applied to three-level SVPWM respectively,whereby enlarging the modulation scope 0≤ MI ≤ 1 . The overmodulation technologies are anglyzed and compared in combination with the three-level features. Finally, an experiment based on V/F feed-forward controlled neutral-point-clamped three-level model inverter using one piece of TI TMS320LF 2407A DSP is carried out. The result confirms that the appli- cation of overmodulation technology in three-level SVPWM is feasible and effective.
