中文摘要

多电平变换器(MLC)已成为高功率及高电能质量应用的标准方案。本文重点探讨了电流型MLC,基于电压源与电流源的对偶原理,分析了其拓扑结构、调制技术及应用前景,旨在为高功率电力电子变换器的研究提供参考。

English Abstract

Multilevel converters (MLCs) have emerged as standard power electronic converters in high power as well as quality demanding applications. They are classified into current-fed MLCs and voltage-fed MLCs. Voltage-fed MLCs have widely researched whereas the current-fed MLCs are the recent topic of research. Based on the principle of duality between voltage and current sources, several current-fed MLC...
