摘要

本文旨在介绍非理想电压条件下PWM-VSI变频器性能的研究结果。除了在Saber模拟器中使用合适的模型进行计算分析外，还进行了实际研究。后者使用商用类型的转换器和可编程的电能质量干扰源。采用理论和实践相结合的方法，考虑不同的非理想供给项目，模拟不同的情况来估计设备的行为。本文重点研究了输入电流和输出电压的特征谐波谱和非特征谐波谱的产生。

Computational and experimental investigation of VSI-PWM frequency converter performance in the context of power quality

This paper aims to present investigation results related to PWM-VSI frequency converters performance under nonideal voltage supply conditions. Besides computational analysis using a proper model in the Saber simulator, practical studies are also given. The later uses a commercial type of converter and a programmable power quality disturbances source. Using both the theoretical and practical way of considering different items of nonideal supply, different situations are simulated to estimate the equipment behavior. The paper focuses the characteristic and noncharacteristic harmonic spectrum generation for both the input current and the output voltage.
