摘要

本文提出了一种新的基于三相源的单相多电平逆变器拓扑结构。所提出的逆变器能够以3:1的比例用两个源产生9级输出。电路由6个单向开关和2个双向开关组成，产生9级输出电压。除了减少设备数量外，突出的优点是它可以在感应负载的四个象限运行，使其适合可再生能源的电网整合。在Matlab/Simulink平台上对逆变器的性能进行了验证。负载电流的总谐波失真低于IEEE-519标准，输出电压电平的提高降低了负载电压的THD。

A New Trinary Source-Based Multilevel Inverter for Renewable Applications

A new single-phase multilevel inverter topology based on the trinary source is presented in this paper. The proposed inverter is capable of generating nine-level output with two sources in a 3:1 ratio. The circuit consists of six unidirectional and two bidirectional switches to produce the nine-level output voltage. The prominent advantage other than the reduced device count is that it works in four quadrants of operation with inductive loads, making it suitable for grid integration of renewable energy sources. The performance of the inverter is substantiated using Matlab/Simulink platform. The total harmonic distortion of the load current is found to be under IEEE-519 standards, and the increased output voltage level reduces the THD in the load voltage.
