Research on a New Hybrid Multi-level Inverter

本文在传统的多电平逆变器拓扑结构的基础上,提出了一种新型的混合多电平逆变器拓扑,并分析了其工作原理,采用了SHEPWM作为该拓扑的调制方式,实现了基于TI DSP TMS320LF2407(A)的单相拓扑的控制,最后通过实验研究证实了该种拓扑的可行性,并给出了一定的结论。

This paper proposes a new hybrid multilevel converter on the base of the traditional multilevel converters, analyzing its pnnciples. The topology uses SHEPWM as the modulation strategy. To get good wave forms, the experiment apparatus applies TI DSP TMS320LF2407（A） as the control chip. At last, the emulation and experiment results is provided, which proves the feasibility of the topology. The end of the paper is the conclusion.
