| 摘 要： | 以高性能数字信号处理器（DSP）TMS320LF2407A为核心生成了基于不对称规则采样法的SPWM波形,并应用TMS320LF2407A控制器的SCI外设接口与PC机RS232接口进行串口通讯,可方便地在PC机串口通讯界面上给定参考频率f以及实时观测一些感兴趣的变量。本文首先分析了算法的原理,然后讨论了基于TMS320LF2407A的软件流程,最后在硬件的基础上给出了实验波形,验证了方案的可行性。

| Abstract: | According to Asymmetry Rule Sampling Algorithmic based on TMS320LF2407A,we generate SPWM waveform.And the system uses the serial communication between the SCI interface of TMS320LF2407 and the RS232 interface of PC.First we analysis the principle of the algorithmic,and then we discuss the software flow based on TMS320LF2407A.At the end we present some experiment waves to validate the design based on the hardware. |
