| 摘 要： | 传统级联型逆变器的每个级联逆变单元通常是完全一样的,这样会限制输出电平的数目。本文提出在级联单元数不变的情况下,通过改变每个级联单元输入电压之间的变比,得到更多的输出电平,使输出电压波形更接近于正弦波。本文介绍了电流SPWM控制方法,对其在不同输出电平时的控制规则进行了描述,并对该控制技术进行了频谱分析。实验结果证明,该方案是正确可行的。

| Abstract: | Each cell of traditional cascaded inverter is accordant,so the number of output voltage levels will be limited. The power quality of the cascaded multilevel may be greatly improved through utilization of different DC voltages on each cell. The article uses current SPWM control method,analyzes its control principle in different output levels,and presents the analysis of the frequency spectrum of the technology. The correctness of analysis is finally verified by experiment. |
