多电平变换器由于具有高功率质量、低开关损耗、高效率等优点而被广泛应用。提出了两种基于五电平子模块结构的级联型功率变换器拓扑。这两种结构进行了分析，在对称和不对称的操作模式，显示优势的电压电平，半导体和驱动器器件的数量，减少面积和重量的转换器的数量。PSCAD/EMTDC仿真环境验证了所提方案的性能。
Multilevel converters have been considered due to several advantages such as high power quality, low switching losses, high efficiency, among others. This paper proposes two new cascaded power converter topologies which are based on five-level sub-module architecture. Both structures are analyzed in symmetrical and asymmetrical operation modes, showing advantages in terms of number of voltage levels, number of semiconductor and driver devices, reducing the area and weight of the converter. The performance of the proposed configurations is verified by considering PSCAD/EMTDC simulation environment.
