A Survey on Neutral-Point-Clamped Inverters
TLDR
The basic operation and the most used modulation and control techniques developed to date of neutral-point-clamped inverters are presented and some technological problems such as capacitor balance and losses are presented.Abstract:
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.read more
