Cascaded- and modular-multilevel converter laboratory test system options: a review. IEEE Access, 9, 44718-44737. https://dx.doi.org/10.1109/ACCESS.2021.3066261||Journal:||IEEE Access||Abstract:||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.||URI:||https://hdl.handle.net/10356/153535||ISSN:||2169-3536||DOI:||10.1109/ACCESS.2021.3066261||Rights:||© 2021 IEEE.
