| 摘 要： | 在研究两电平逆变器与三电平逆变器之间SVPWM本质的基础上,提出了一种基于两电平空间矢量的三电平空间矢量算法.三电平空间矢量控制中分区算法可由两电平矢量作用时间的计算结果获得,并且这两种逆变器的矢量作用时间可以通过一个线性矩阵转换.为了分析三电平逆变器的脉冲序列模式,按照矢量之间切换的可能性,提出了一种新的可用于描述矢量开关序列的分类标准.针对传统的和改进的作用序列进行逆变器输出谐波的评估.文中所提的各种理论与算法都可以非常容易地推广到更多电平的系统中.为了验证所提算法的正确性,进行了实验验证. |

| Abstract: | Based on the intrinsic relationship between SVPWMs for two-level inverters and three-level inverters, a novel SVPWM control algorithm is proposed for three-level. The dwell time of voltage vector for three-level inverter can be acquired from counterpart for two-level inverter by using a linear transformation. Aiming to analysis the output PWM sequence of three-level inverter, a novel classification standard of voltage vector is proposed. Based on evaluating the PWM sequences, a novel PWM sequence is given, ... |
