基于DSP28335的三相SPWM波的实现

摘要

针对传统的逆变电路，介绍了利用TI公司的DSP专用芯片TMS320F28335，通过不对称规则采样法来采样来输出三相SPWM波，并给出了部分源代码和实验结果。实验结果表明，该方法生成的SPWM波能满足逆变系统的需要，具有高效、简洁、实时性强等优点。%According to the traditionaI inverter circuit,this paper introduces the use of TI company's DSP chip TMS320F28335,to sampIe the output three-phase SPWM wave by asymmetric reguIar sampIing,and part of the source code and experimentaI resuIts are given.The experimentaI resuIts show that,the method generates the SPWM wave can meet the need of inverter system,has the advantages of high efficiency,simpIe,reaI-time.
