摘要 本文提出了一种新型先进的堆叠式多单元逆变器拓扑，该拓扑通常适用于与少量开关相关的大量步数。与传统的飞跨电容器多节和堆叠式多节（SM）逆变器相比，所提出的逆变器可将输出电压电平数量和RMS值加倍，改善输出电压频谱，减少组件数量和额定值，并可提供存储能量和飞跨电容器额定值。这些改进是通过在传统 SM 逆变器结构中仅添加四个低频开关来实现的。使用 MATLAB/SIMULINK 软件对建议的拓扑进行仿真，仿真结果表明新型转换器的良好性能。此外，还给出了所提出的拓扑原型的实验结果，以验证其实用性。
Abstract In this paper, a new advanced topology of stacked multicell inverter is proposed which is generally suitable for high number of steps associated with a low number of switches. Compared with traditional flying capacitor multicell and stacked multicell (SM) inverters, doubling the number of output voltage levels and the RMS value, ameliorating the output voltage frequency spectrum, decreasing the number and rating of components, stored energy and rating of flying capacitors are available with the proposed inverter. These improvements are achieved by adding only four low-frequency switches to the traditional SM inverter’s structure. The suggested topology is simulated using MATLAB/SIMULINK software, and simulation results are presented to indicate well-performance of the novel converter. In addition, the experimental results of proposed topology prototype have been presented to validate its practicability.
