摘要
逆变器是工业生产中的重要部分,如今主流使用的逆变器一般为三相桥式PWM逆变器,其控制技术对逆变器输出性能影响较大。基于此,对PWM控制技术进行深入研究,分析了该控制技术的数学模型,并用Simulink进行波形仿真分析,依据谐波产生频次提出SHEPWM技术对相关低次谐波进行抑制,并给出相应流程图。
Inverter is an important part of industrial production.Nowadays,the mainstream inverters are generally three-phase bridge PWM inverters,whose control technology has a significant impact on the output performance of the inverter.This article is committed to in-depth research on PWM control technology,analyze the mathematical model of the control technology,and use Simulink to conduct waveform simulation analysis.Based on the frequency of harmonic generation,the SHEPWM technology is proposed to suppress relevant low order harmonics,and the corresponding flow chart is given.
