摘要
本文首先介绍了多电平变换器的产生背景和发展、多电平变换器在风力发电中的应用,然后总结了现有的多电平变换器存在的问题和不足。在此基础上,重点研究了一种新型的模块化多电平变换器的拓扑结构和工作原理。此种结构简单、灵活,十分适用于直驱型风力发电系统。
This article firstly describes the background,development and application of multi-level conventer in wind-power system,then summarizes the existing problems of the existing multi-level converter.On this basis,we proposed a new modular multilevel inverter＇s topological structure and working principle.As this structure is simple and flexible,it is suitable for direct-drive wind power system.
