摘要

多电平逆变器在包括可再生能源在内的现代工业场景中有着广泛的应用。它们可用于高压和高功率应用。输出电压包含较少的谐波，它提供了更高的效率，相比传统的逆变器。通过实现不同的开关算法，可以用较少的THD产生输出电压，并且可以采用不同的拓扑结构，以较少的半导体开关数量实现更高电平的逆变器。本文提出了一种改进的多电平逆变器拓扑结构，减少了开关数，并通过粒子群算法降低了电压THD。确定了开关损耗和效率。

PSO Based Improved Topology for MLI Considering Low THD and Low Switching Loss

Multilevel inverters have wide range of applications including renewable energy in modern industrial scenario. They can be used in high voltage and high power applications. The output voltage contains lesser harmonics and it provides greater efficiency as compared to classical inverter. By implementing different switching algorithms the output voltage can be generated with less THD and different topologies can been adopted for higher level inverter with less number of semiconductor switches. In this paper an improved topology of multilevel inverter has been proposed with reduced switch count, and by implementing PSO algorithm the voltage THD has been reduced. The switching losses and efficiency has determined.
