摘要

Due to multilevel inverters can have more levels of output voltage at the output waveform, closer to sine waves, and with small output waveform THD, and low voltage stress, low system advantages of EMI, multilevel inverters are widely recognized, and get a certain application. Based on the analysis of the characteristics of the basic multi-level inverter topology and the scope of application, this paper explores the idea and method of multi-level inverter topology using multi-terminal switch network. By comparing the new topology and basic topology, it can be seen that this new multi-level inverter topology is easy to expand, requiring small filter inductance volume and inductance, loss and low cost, which is an important direction for the development of topological circuits. The new multi-level topology has broadened the research scope of multi-level inverter topology and created new ideas and directions for multi-level topology research, which provides theoretical guidance for further scientific research and engineering applications.
