摘要

多电平逆变器（MLI）是直流-交流转换器系列中重要的一种，在中低功率应用中被广泛接受。本文为多电平开发了一种 "新型逆变器拓扑结构"。这项工作的主要目的是在相当高的输出电压水平下减少开关数量，同时减少所需的栅极驱动。论文还旨在分析所提出的新型多电平逆变器拓扑结构的性能。拟议的拓扑结构可产生 15 级输出。只需使用八个开关器件、四个二极管和三个不对称源。因此，减少了安装空间和成本。设计的拓扑结构使用普通 "脉宽调制（PWM）"和 "正弦脉宽调制（SPWM）"进行了仿真。两种模拟结果都针对 "输出电压、电流、总谐波失真（THD）"进行了讨论。此外，还对所开发的拓扑结构与其他一些最新的 MLI 拓扑结构进行了比较研究。

Performance Analysis of a Novel Multilevel Inverter with Reduced Number of Switches

Multilevel inverters (MLI) are important and widely accepted under DC to AC converter family for medium and low power applications. In the paper a “new inverter topology” for multi-level is developed. The primary purpose of the work is to reduce the switch count number for considerable level of output voltage and also to reduce gate drives required. It also aims at analysis of performance of proposed topology of new multilevel inverter. Output of fifteen stages is generated from the proposed topology. For which only eight switching devices, four diode and three asymmetrical sources are used. Thus, the space and cost for installation is reduced. The designed topology is simulated with normal “pulse width modulation (PWM)” as well as “sinusoidal pulse width modulation (SPWM)”. Both the Simulation results are discussed with respect to “output voltage, current, Total Harmonic Distortion (THD)”. A comparative study is also made between the topology developed with few other latest MLI topologies.
