| 摘 要： | 提出了一种简化的五相三电平H桥逆变器空间矢量PWM算法.该方法采用相移SPWM思想,将五相三电平H桥逆变器作为两个由单桥臂组成的五相分别予以控制.分析选择合理的工作电压矢量及开关作用顺序,计算开关周期内的各工作电压矢量的作用时间,仿真和实验结果均验证了文中提出的空间矢量PWM算法可以减小输出电压谐波.

| Abstract: | As for the five-phase three-level H-bridge inverter,the number of its output voltage vectors is so large that it's hard to apply the traditional SVPWM algorithm method into use.In this paper,a simplified SVPWM algorithm suitable to the five-phase three-level H-bridge inverter is proposed.Based on the phase-shift SPWM method,the five-phase three-level H-bridge inverter can be taken as two single five-phases,and each can be controlled alone.The work voltage vectors and the switching sequence is chosen rationa... |
