中文摘要

维也纳整流器固有的中点电压波动会影响输入电流质量,但现有文献缺乏深入分析。本文基于三电平到两电平空间矢量调制变换,提出了一种评估中点电压波动对输入电流质量影响的新方法。

English Abstract

The inherent neutral-point (NP) voltage fluctuation of the Vienna rectifier could have side effects on the input current quality. However, such effects have not been thoroughly analyzed in the literature yet. In this article, based on the three-level to two-level space vector modulation transformation, a novel method to evaluate the influence of the NP voltage fluctuation on the input current qual...
