中性点箝位（NPC）逆变器是在大功率应用（几兆瓦）中使用最广泛的多电平逆变器拓扑。本文介绍了一个非常简单的方式的基本操作和最常用的调制和控制技术开发的日期。特别注意的是在半导体损耗分布，并提出了一种有源NPC逆变器，以克服这个问题。本文讨论了它的主要应用领域，并提出了电容平衡和损耗等技术问题。
Neutral-point-clamped (NPC) inverters are the most widely used topology of multilevel inverters in high-power applications (several megawatts). This paper presents in a very simple way the basic operation and the most used modulation and control techniques developed to date. Special attention is paid to the loss distribution in semiconductors, and an active NPC inverter is presented to overcome this problem. This paper discusses the main fields of application and presents some technological problems such as capacitor balance and losses.
