Abstract

Multilevel Inverters (MLIs) are becoming more and more popular in medium and high power applications. This is due to several inherent advantages of MLI over two-level inverters such as high-quality output, lower device ratings, and several others. While the classical topologies are still having applications in most of the key areas, there is a growing interest in newer multilevel topologies with an objective of reducing power semiconductor device count, gate drivers and/or isolated DC sources. In this paper, a comprehensive review of some of the recently proposed newer multilevel inverter topologies with the abovementioned objectives is presented. In this article, a detailed investigation in terms of total power semiconductor switch count, number of DC sources, passive component requirement, highest switch voltage rating, total standing voltage etc. has been presented.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
