Abstract

The Multilevel DC-Link Inverter (MLDCLI) is an important interface between solar panels and residential AC supply systems. In this paper, a MLDCLI using three asymmetric DC sources is designed to get a 15-level output voltage. This converter is controlled using a Simplified Gate Pulse Generation (SGPG) technique. Further, modified Nearest Level Modulation (mNLM) is applied to improve THD if there is a change in the ratio of DC voltage sources. To get the best value for THD, the gradient angles automatically change when the voltage in one of the DC sources changes. The results were verified using MATLAB and followed by experiments on a hardware prototype.

可变直流电压源的多电平直流逆变器的THD改进
多电平直流逆变器(MLDCLI)是太阳能电池板与住宅交流供电系统之间的重要接口。本文设计了一个使用三个非对称直流电源的MLDCLI,以获得15电平的输出电压。该变换器采用简化门脉冲产生(SGPG)技术进行控制。此外,如果直流电压源的比例发生变化,则应用改进的最邻近电平调制(mNLM)来改善THD。为了获得最佳的THD值,当其中一个直流电源的电压变化时,梯度角会自动改变。利用MATLAB对结果进行了验证,并在硬件样机上进行了实验。
