| 摘 要： | 对三电平逆变器（SVPWM）经典算法和改进算法中电压空间矢量所在的扇区判断、所在的三角形的判断进行了详细的研究,并在确定了矢量所在的位置后根据伏秒特性计算各矢量的作用时间。最后,通过MATLAB对三电平逆变器在空间矢量控制算法下产生的线电压和相电压进行了仿真,并对其产生的谐波进行了分析,通过比较证明了三电平和两电平相比,三电平输出谐波分量较少,能够产生较高的功率质量。 |

| Abstract: | How to determine the section and triangle where the voltage space vector locates in the classical SVPWM algorithm and the improved algorithm for a three-level inverter was studied.The running time was calculated by volt-second characteristic after the judgment of the location of the vector.Further more,both the line voltage and phase voltage obtained by the three-level inverter space vector control algorithm was simulated with MATLAB.The harmonics was alos analyzed.By comparison,it was found that the harmonic of three-level output is less,thus producing high power quality. |
