| 摘 要： | 基于正弦脉宽调制技术(SPWM)的逆变电路应用,利用傅里叶变换对电压型SPWM逆变电源的输出电压进行了分析,并提出了易于工程实现的谐波抑制方法。分别从调制法和计算法出发,采用在正弦调制波中叠加入一定比例的零序谐波和特定谐波消除PWM法,并且利用Matlab/Simulink进行了仿真,并且做了对比试验,验证了抑制方法的正确性。

| Abstract: | Inverter circuit based on SPWM technology is widely used , this paper analyzes the output voltage of voltage-SPWM inverting power using Fourier transform, and presents two kinds of harmonic ristraint method which is easy to achieve. From modulation method and calculation method, this paper adopts that injecting a certain percentage of zero-sequence harmonics in the sine modulated wave and selected harmonic elimination PWM method, also simulates using Matlab/simulink, and experimentizes contrastively, the va... |
