ABSTRACT In this paper, a new cascade multilevel inverter based on series connection of several basic units is proposed. The basic topology consists of 5 dc voltage sources and 12 switches. The required mathematical analysis consisting of voltage on switches, power losses and the values of dc voltage sources is provided. To verify the advantages of proposed topology, the suggested structure is compared with other multilevel inverter topologies in terms of used dc voltage sources, switches, voltage on switches and the number of on-state switches. The proposed structure uses the least numbers of dc voltage sources and switches compared to other multilevel inverters for the same number of levels. Also, voltage rating on the switches in the proposed topology is less than other topologies. These characteristics cause the weight, size and cost of proposed topology to be reduced. The proposed inverter is implemented using experimental setup. The experimental results verify the performance of proposed structure.

具有低功耗电子设备的新型基本单元和级联多电平逆变器

摘要 在本文中，提出了一种基于多个基本单元串联的新型级联多电平逆变器。基本拓扑由 5 个直流电压源和 12 个开关组成。提供了所需的数学分析，包括开关上的电压、功率损耗和直流电压源的值。为了验证所提出的拓扑结构的优点，在所使用的直流电压源、开关、开关上的电压和导通状态开关的数量方面，将所建议的结构与其他多电平逆变器拓扑进行了比较。与具有相同电平数的其他多电平逆变器相比，所提出的结构使用最少数量的直流电压源和开关。此外，建议拓扑中开关的额定电压低于其他拓扑。这些特性导致重量，建议拓扑的大小和成本要减少。所提出的逆变器是使用实验装置实现的。实验结果验证了所提出结构的性能。
