| 摘 要： | 增加逆变器的电平数是将逆变技术应用到高压大容量场合有效的解决方案.但是随着电平数的增加,其空间矢量调制算法(SVPWM)也越来越复杂.本文在研究2电平逆变器与任意电平逆变器之间的SVPWM本质联系的基础上,提出了一种基于矩阵变换的多电平SVPWM算法.采用最近相邻三矢量(NTV)合成原则,任意电平SVPWM控制中矢量选择和作用时间都可由2电平逆变器的矢量作用时间的计算结果获得,并且推导出任意电平SVPWM算法与2电平SVPWM算法可以通过一个线性矩阵转换.最后,仿真分析了算法的可移植性问题,实验验证了算法满足多电平控制系统中的实时性要求.

| Abstract: | Increasing levels of inverters is a good solution to inverters used in high power,high voltage application.But the space vector modulation(SVPWM) of multi-level inverters is more and more complex as level of inverter increasing.Based the intrinsic relationship between SVPWMs for two-level inverters and arbitrary level inverters,a novel SVPWM control algorithm is proposed for arbitrary-level in this paper.Considering that nearest three vectors(NTV) is used to synthesis reference vector,the dwell time of volt... |
