Throughout this paper, a single-source hybrid switched-capacitor multilevel inverter is presented. The suggested topology is comprised of switched-capacitor modules. In this topology, two types of switched-capacitor modules are utilized: 1) basic module (BM) and 2) auxiliary units (AUs). By adding more AUs to the proposed topology, the voltage levels can be increased. By taking advantage of the switching procedure, three various configurations are made for the suggested MLI, in which the voltages of the capacitors are determined differently. Hence, in each configuration, according to the voltages of capacitors, different output voltage levels with different maximum output voltage and total standing voltage of switches are attained. To show the superiority of the proposed topology, a comprehensive comparison is made in terms of the number of DC voltage sources, power switches, capacitors, and diodes. Moreover, to investigate the performance of the suggested topology, a sample circuit with all configurations is simulated in MATLAB/Simulink. Finally, the experimental results are demonstrated to illustrate and verify the feasibility of the proposed inverter.

在本文中，介绍了一种单源混合开关电容多电平逆变器。建议的拓扑结构由开关电容模块组成。在此拓扑中，使用了两种类型的开关电容器模块：1) 基本模块 (BM) 和 2) 辅助单元 (AU)。通过向建议的拓扑添加更多的 AU，可以增加电压电平。通过利用切换过程，为建议的 MLI 进行了三种不同的配置，其中电容器的电压以不同的方式确定。因此，在每种配置中，根据电容器的电压，可以获得不同的输出电压电平，具有不同的最大输出电压和开关的总耐压。为了显示所提出拓扑的优越性，从直流电压源、电源开关、电容、二极管的数量上进行了综合比较。此外，为了研究建议拓扑的性能，在 MATLAB/Simulink 中对具有所有配置的示例电路进行了仿真。最后，通过实验结果来说明和验证所提出逆变器的可行性。
