Development and Current Status of Multi-Level Converter

Abstract:

The multi-level converter is one of the focuses in the current high-voltage high-power field of power conversion, and is found widely application in high power drive system. It generated so far for nearly three decades of history. During this period a large number of multi-level topology appeared, there are three most commonly used, which are diode clamped, capacitor and cascaded H-bridge. In this paper, the development of the multi-level converter is reviewed. The structure of three multi-level converter topologies are given, and then their advantages and disadvantages are given by analyzing and comparing their characteristics. Finally, a new modular multi-level converter (MMC) is introduced which is one of research focus of multi-level converter field at present. Its structure and working principle are described in detail. Multi-level converters will continue to be developed to meet the demand of high-voltage and high power applications.
