摘要
提出了一种软件生成三相SPWM波的新方法。首先 ,阐述了对称规则采样法和基准正弦函数表 ;然后 ,介绍了一个通用变频器的应用实例及生成三相SPWM的程序。实验结果显示 ,该变频器能满足实际应用的要求。
This paper presents a kind of new method to generate the three-phase SPWM wave by software.At first,it introduce symmetry regular-sampling and benchmark sine function table.Then,it presents an application example of universal transducer and a program of generating three-phase SPWM.The experimental results show that the transducer can satisfy the need of actual application.
