摘要
该文给出了基于DSP形成SPWM产生的原理和具体实现过程,应用三阶式脉宽调试法计算出各交点的数值形成可查询表格,将其数值TI公司推出的控制芯片TMS320LF2407存储器中,通过程序读取数值,再经过D/A转换,即可形成所需的SPWM波。
This paper gives the SPWM formation principle and realization process based on the DSP, application of three stage pulse width adjustment method to calculate the numerical value of each node can query table form, the numerical control chip TMS320LF2407 memory produced by TI company, the program reads the value, and then through the D/A conversion, the formation of SPWM wave can be required
