基于无扇区判断的SVPWM控制Z源逆变器的研究

Research on the Z-Source Inverter Based on the SVPWM Control without Sector Judgment

主要研究的是SVPWM控制技术在三相Z源逆变器中的应用,并分析了在不同的直通占空比下逆变输出的电压大小情况。采用新型的SVPWM算法,无需复杂的坐标变换和扇区判断。在MATLAB/Simulink中对其进行分析和仿真实验,结果证明理论的正确性。

This paper mainly studied the application of the SVPWM control technology to the three-phase Z-source inverter, comparing and analyzing voltage output of the inverter in different direct duty ratios. This study adopteda new type of SVPWM algorithm, without complex coordinate transformation and sector judgment. Analysis and simulation experiments were made in MATLAB/Simulink, and the results verified the correctness of the theory.
