摘要
介绍了以载波频率ωs为基准异步SPWM波的谐波分析方法。并且分析了单相、三相逆变器的单极、双极性SPWM波形的谐波特性．为谐波抑制和谐波网络的设计提供了参考，其结论也适合于同步调制模式。
This paper introduces a harmonic analysis method for asynchronous SPWM on the basis of carrier frequency ωs. And the harmonic characteristics of unipolarity, bipolarity SPWM wave of single-phase,three-phase inverter are analyzed. It provides the technical reference for harmonic suppression and filter network design. The obtained results also fit to the synchronous modulation model.
