摘要
介绍了脉宽调制(PWM)的原理,重点分析了各种正弦脉宽调制(SPWM)方法,其中包括自然采样法,规则采样法等,并利用基于DSP的脉宽调制实验平台对各种SPWM方法进行了比较分析,得出了一些有益的结果。
This paper introduces the theory of PWM control, and specially analyses some methods of SPWM, including Natural Sampling, Regular Sampling, and so on. Basing on the experimental patform of SPWM on DSP, the paper compares each method of SPWM and achieves some useful results.
