多电平转换器在中压和低压应用中都得到了普及。为了找出各种多电平电压源转换器拓扑之间的联系并揭示如何获得新的拓扑，本文提出了四种推导多电平转换器拓扑的方法。许多现有的拓扑以及新的拓扑都可以通过本文提出的方法导出。本文还通过数学模型和实例研究了决定其可用性的多电平变换器的基本特性，例如直流母线中性点电压平衡和飞跨电容器电压控制。预计将基于本文的工作为新兴应用发明更多新的拓扑。
Multilevel converters have gained popularity in both medium voltage and low voltage applications. To find out the connections between various multilevel voltage-source converter topologies and to reveal how to obtain new topologies, this paper has presented four methods to derive multilevel converter topologies. Many existing topologies as well as new topologies can be derived with the methods presented in this paper. The fundamental characteristics of the multilevel converters which determine their usability such as dc-link neutral point voltage balancing and flying capacitor voltage control are also investigated in this paper with a mathematical model and an example. It is expected that more new topologies will be invented based on the work in this paper for emerging applications.
