摘要

提出了一种基于最大功率点跟踪的光伏系统中开关数最少的新型单相11电平逆变器。本文提出的单相十一电平逆变器是在传统逆变器拓扑的基础上发展起来的。多电平逆变器是一种有效的、实用的提高功率和降低交流波形谐波的解决方案。采用脉冲宽度调制控制方案的单相11电平逆变器和与三角载波信号幅值相同的3个参考信号产生PWM信号。由于有效地利用了开关脉冲调制，谐波被识别在最低水平。使用MATLAB/SIMULINK对输出进行清晰监控。

Standalone photovoltaic system with MPPT techniques on single-phase eleven-level inverter for utility applications

This paper presents a Maximum power point tracking based new single-phase eleven-level inverter with minimum number of switches in photovoltaic systems. The proposed single-phase eleven-level inverter has been developed from the conventional inverter topology. Multilevel inverter is an effective and practical solution for increasing power and reducing harmonics in AC waveforms. The single-phase eleven-level inverter with Pulse Width Modulated control scheme and three reference signals that are identical to the amplitude of the triangular carrier signal were used to generate the PWM signals. The harmonics were identified at minimum level due to efficient use of switching pulse modulation. The output is clearly monitored using MATLAB/SIMULINK.
