Abstract

The advent of high power and medium power appliances has given substantial importance to Multilevel Inverters (MLI) in recent times. The MLI is widely used in driving AC loads which requires to be operated with low harmonics. In this paper, the various MLI topologies and the modulation techniques implemented on MLIs are reviewed. While reviewing the various MLI topologies, they are categorized into symmetrical type and asymmetrical type. All the existing MLIs topologies and those that are developed in future can be categorized into one of these two categories. A comprehensive review is done of these topologies to examine the various performance parameters. The modulation techniques are also classified into fundamental switching frequency (FSF) modulation techniques and high switching frequency (HSF) modulation techniques. This classification provides an easy understanding of the concepts that are conveyed by MLI. This paper also gives a broad understanding of the various features of each modulation technique.
多电平逆变器:最新拓扑结构和新调制技术综述
近年来,大功率和中功率电器的出现使多电平逆变器(MLI)得到了极大的重视。MLI广泛应用于要求低谐波运行的交流负载的驱动。本文综述了各种MLI拓扑结构和在MLI上实现的调制技术。在回顾各种MLI拓扑结构时,将它们分为对称型和不对称型。所有现有的mli拓扑和将来开发的mli拓扑都可以归为这两类之一。对这些拓扑进行全面的检查,以检查各种性能参数。调制技术又分为基频(FSF)调制技术和高开关频率(HSF)调制技术。这种分类便于理解MLI所传达的概念。本文还对每种调制技术的各种特性进行了广泛的了解。
