资料介绍

多电平逆变器具有电压等级、逆变效率和输出电能质量高以及电磁干扰小等优点。在中高电压等级的电能变换场合有着广阔的发展前景。详细阐述了多电平逆变器传统型拓扑的优缺点和适用范围,并重点研究了几种新型拓扑的工作原理。通过对比新型拓扑与传统型拓扑可知,减少开关器件的使用、简化电路与调制策略是拓扑电路发展的一个重要方向,多电平逆变器拓扑结构向着复合性、多样性方向的趋势发展。

Multilevel inverter features higher voltage level, inverting efficiency, quality of output electric energy, and less electromagnetic interference, so it possesses broad developing prospects in medium and high voltage level electric energy conversion occasions. The advantages and disadvantages of traditional topology and applicable scope of multilevel inverter are described in detail, and the operational principles of several novel types of topologies are research emphatically. By comparing the new topology and traditional topology, it is known that reducing the use of switching devices, simplifying circuitry and modulation scheme are the important direction for developing topological circuit; composite and diversity are the developing trend of the topologic...
