ABSTRACT

This paper proposes a new cascaded switched-capacitor (SC) multilevel inverter (MLI). This inverter uses a suitable process to charge/discharge the capacitors to keep them balanced. Also, in the proposed MLI, fewer power electronic elements are required, and the value of the blocked voltage on switches also decreased. Six methods are proposed to determine the magnitude of the dc power supplies. These methods are compared to each other. A 17-level inverter is experimented to show the performance of the proposed topology

基于开关电容的多电平逆变器，减少了元件数量

摘要

本文提出了一种新的级联开关电容（SC）多电平逆变器（MLI）。该逆变器使用适当的过程对电容器进行充电/放电以保持它们的平衡。此外，在所提出的 MLI 中，需要更少的电力电子元件，并且开关上的阻断电压值也降低了。提出了六种方法来确定直流电源的大小。这些方法相互比较。对 17 电平逆变器进行了实验，以显示所提出拓扑的性能
