级联多电平变流器(CMC)和模块化多电平变流器(MMC)的子类别在高压直流连接和静止补偿器中的广泛应用说明了它们的日益重要。目前正在研究如何将这些复杂的硬件和软件用于除基频功率注入之外的各种电网支持服务，这需要改进对非传统任务的控制。为了验证这些结果，通常需要小规模的实验室硬件原型。这样的系统已经由全球各地的许多研究团队建造，并且越来越多地在商业上可用。很少有出版物详细介绍原型CMC的建造方案，而且缺乏关于设计考虑和从建造过程中吸取的经验教训的信息，这将阻碍这些重要单元的研究和最佳应用。本文回顾了各种选择，给出了主要研究团队的关键例子，并总结了在开发测试台时获得的知识，以澄清在构建实验室规模的CMC时的设计考虑。
The increasing importance of cascaded multilevel converters (CMCs), and the sub-category of modular multilevel converters (MMCs), is illustrated by their wide use in high voltage DC connections and in static compensators. Research is being undertaken into the use of these complex pieces of hardware and software for a variety of grid support services, on top of fundamental frequency power injection, requiring improved control for non-traditional duties. To validate these results, small-scale laboratory hardware prototypes are often required. Such systems have been built by many research teams around the globe and are also increasingly commercially available. Few publications go into detail on the construction options for prototype CMCs, and there is a lack of information on both design considerations and lessons learned from the build process, which will hinder research and the best application of these important units. This paper reviews options, gives key examples from leading research teams, and summarizes knowledge gained in the development of test rigs to clarify design considerations when constructing laboratory-scale CMCs.
