| 摘 要： | 多电平PWM控制技术是多电平变换器研究的核心内容之一。基于传统两电平PWM技术的研究经验，经过近十几年的发展，多电平PWM控制技术己形成了几类不同的实现方法，同时新的控制方法还在涌现。但一直以来多电平的电压平衡控制就是研究的热点。本文提出了两种基于三电平SVPWM的中点电压平衡控制方法，详细介绍了每种算法的具体操作过程，并给出了改进的思路。

| Abstract: | The PWM control is key technology in a multilevel converter.Multilevel PWM control technology has developed different ways to accomplish on the basis of traditional two level PWM methods during past decade years.The neutral-point-balance control scheme is always the hot issues;it presents two kinds of control algorithms to fulfill this system,introduces concrete fulfillment process of each kind of the algorithm,and presents a method to improve it. |
