摘要

本文提出了一种用于三电平NPC变换器直流链路电压平衡的控制方法。讨论了变换器的几个相关特性，如电压能力、谐波失真和功率损耗。与其他技术相比，谐波失真水平较低，半导体损耗(传导和开关)较低，结果与文献中其他技术相近。给出了实验结果和仿真结果。

A control technique to balance the voltage of DC-link for three-level NPC converter

This paper proposes a control to balance the voltages of Dc-link for three-level NPC converter. Several relevant characteristics of the converter are addressed, such as voltage capability, harmonic distortion, and power losses. Compared to other techniques, the level of harmonic distortion was lower and the semiconductor losses (conduction and switching), the result was closed to other techniques present in the literature. Experimental results as well as simulated ones are presented.
