Having a reduced number of switches and isolated DC sources yet generating a higher number of voltage levels has been always the challenge when selecting the appropriate Multilevel Inverter (MLI) topology. Nowadays, Single-DC-Source Multilevel Inverter (SDCS-MLI) topologies are being considered as more suitable for many power system applications such as Renewable Energy (RE) conversion systems and electrified transportations compared to the Multiple-DC-Source MLIs (MDCS-MLIs). Moreover, increasing the power rating and minimizing the switching frequency while maintaining reasonable power quality using a SDCS-MLI is an important requirement and a persistent challenge for the industry. Thus, this paper presents a general review on the available SDCS-MLI topologies and future trends. Existing solutions are discussed and analyzed based on their topologies, number of output voltage levels, number of active/passive components, advantages/limitations, maturity, and industrial applications. Furthermore, recommendations for future research and development are suggested in this paper.

单DC源多电平逆变器的评论:拓扑,挑战,工业应用和建议

选择合适的多电平逆变器(MLI)拓扑时,减少开关数量和隔离直流电源,同时产生更高数量的电压一直是挑战。如今,与多直流源MLI(MDCS-)相比,单直流源多电平逆变器(SDCS-MLI)拓扑被认为更适合许多电力系统应用,例如可再生能源(RE)转换系统和电气化运输。 MLIs)。此外,使用SDCS-MLI增加功率额定值并最小化开关频率,同时保持合理的功率质量,对于工业来说是一项重要的要求和持续的挑战。因此,本文对可用的SDCS-MLI拓扑和未来趋势进行了概述。根据现有解决方案的拓扑,输出电压电平数量,有源/无源组件数量,优势/局限性,成熟度和工业应用来讨论和分析现有解决方案。此外,本文还提出了对未来研究和发展的建议。
