摘要
给出了一种以TI DSP芯片TMS320LF2407A为核心的SPWM等面积生成法。首先分析了等面积SPWM的算法原理,然后讨论了基于TMS320LF2407A的软件流程,并给出了部分C程序源代码,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。实验表明用该方法控制逆变器所输出的电流波形在较宽的调频范围内都非常接近于正弦波。
A SPWM, signal equivalent area generation method based on TI DSP chip TMS320LF2407A is introduced. First the principle of the algorithmic of area equivalent generation method was analyzed. Then the software flow based on TMS320LF2407A was discussed, and some C program source codes were given. In the end, some experiments waves were present to validate the design based on the hardware. The experiment indicate that with this method control inverter output current waveform is more close to sine wave in wider range of frequency.
