摘要

多电平变换器在电机驱动、可再生能源系统和配电系统等大功率应用中越来越受欢迎。在所有调制技术中，选择性谐波消除方法在低开关频率下提供高质量的电压波形，因此特别适用于大功率应用。本文提出了一种新的解析式，可以计算出五电平变换器开关角的精确值。在对所提出的方法进行数学描述后，本文报告了模拟和实验结果以及显示可实现结果的分析。

Selective Harmonic Elimination in a 5-Level Single Phase Converter with FPGA Based Controller

Multilevel converters are becoming popular in high-power applications such as motor drives, renewable energy systems and distribution systems. Among all modulation techniques, selective harmonic elimination methods offer high quality voltage waveforms with operations at low switching frequency, hence, they are especially suitable for high-power applications. In this paper, a new analytical expression for the SHE problem formulated for a five-level converter is introduced, which is able to calculate the exact value of the switching angles. After a mathematical description of the proposed approach, this manuscript reports simulation and experimental results and analysis showing achievable results.
