摘要

多级逆变器(MLI)用于需要非常高电压和大电流的场所或行业。与单电平变换器相比,多级逆变器拓扑结构具有多种优点。这些优点是:提高输出电压,减少总谐波失真(THD),减少电磁干扰(EMI)的产生等。多级逆变器的关键特性是降低各功率器件上的电压应力。这种减少是由于在直流总线上使用了几个可用的电平。多级逆变器的曙光

THD Analysis of Cascaded Multi-level Inverters using different PWM Techniques
Multi-level inverters (MLI) are used in places or industries that require very high voltage and huge current. Multi-level inverter topologies have various advantages over single level converters. These advantages are like: rise in output voltage, reduction in the total harmonic distortion (THD), reduction in electro-magnetic interference (EMI) generation etc. Key attribute of a multi-level inverter is the reduction in the voltage stress on each power device. This reduction is due to the use of several levels available on the DC bus. The dawn of multi-level inverter
