| 摘 要： | 提出了一种多电平逆变器SVPWM算法。该算法可以根据参考电压矢量的幅度和相位方便地选择3个邻近的基本空间电压矢量并计算出其作用时间。该算法不但适用于三电平逆变器，而且对更多电平数的多电平逆变器同样有效。利用提出的简化算法对一个三电平逆变器进行了仿真，仿真结果验证了其正确性。

| Abstract: | It proposed a SVPWM algorithm for three-level inverters. In the new system, the original voltage is represented as thecoordinate scale and the nearest composed vector can be selected easily. The dwelling time of each vector can be simply calculated for eitherthree-level inverters or inverters with more levels. A three-level inverters simulation is completed to realize the proposed algorithm. Thesimulation results verify the validity of the proposed algorithm. |
