摘要
分析了二极管钳位型三电平逆变器的结构及工作原理,以及三电平逆变器中各个合成空间矢量的作用时间,并以此作为调制信号,从信号处理的角度来理解三电平空间矢量脉宽调制(SVPWM)技术,提出了一个便于数字编程实现的三电平SVPWM控制算法。全面阐述了仿真系统搭建的理论依据,通过MATLAB仿真,得到了期望的仿真波形,验证了该算法的可行性。
The basic structure and control principles of the three-level NPC inverters are described, the control time of basic space vector, looks up it as modulation signal is analysed. A real control algorithm of three-level SVP- WM which is facilitated for digital programming is given out from the aspect of signal process. The experimental result demonstrates the feasibility of this algorithm which simulated in MATLAB/Simulink.
