中文摘要

多电平逆变器在工业和研究领域备受关注。尽管经典拓扑在高功率中压应用中表现出色,但业界正积极探索新型拓扑。近期研究的核心目标是相较于经典拓扑,显著减少整体器件数量,以提升功率密度并降低成本。

English Abstract

Multilevel inverters have created a new wave of interest in industry and research. While the classical topologies have proved to be a viable alternative in a wide range of high-power medium-voltage applications, there has been an active interest in the evolution of newer topologies. Reduction in overall part count as compared to the classical topologies has been an important objective in the recen...
