阐明了常用的不对称规则采样法SPWM的采样次数多、占用处理器资源大的问题,详细分析了能够解决这一问题的线性组合采样法的整体原理。通过双顶点采样法与对称规则采样法的比较,引出新型线性组合采样法,并利用Matlab强大的数值计算功能对几种采样法SPWM波行进行谐波分析,同时给出了分析过程中的关键程序段。分析结果证明了线性组合采样法的有效性,也证明了双顶点采样法是不实用的。

This article first illustrates the shortcoming of the asymmetric regular sampling SPWM, it requires a large sampling numbers, and so occupy a large processor resources. Then a detailed analysis of the linear combination sampling method to solve this problem is given. Through the comparison of symmetric regular sampling method and two-vertex sampling method, this article leads to novel linear combination sampling method, and then uses Matlab numerical calculation functions for harmonic analysis of several sampling SPWM wave, also finally gives a few key procedures in the analysis process. The analysis results validated the linear combination sampling method, it also proved that the two-vertex sampling method is not practical.
