微机控制率频调速系统SPWM序列的一种新算法

A New Algorithm of SPWM Sequence Used in the VF SR System with Microcomputer

介绍了计算机控制的交流电动机变频调速系统ＳＰＷＭ序列的一种新算法。该算法改进了规则采样法。对面积误差和谐波抑制能力进行了分析。

This paper introduces a new algorithm of SPWM sequence used in the AC motor's VF SR system with microcomputer, in which regular sampling can be improved. It also makes an analysis of area error and harmonic elimiation feature.
