空间向量脉宽调制原理及实现

The Principle and Implementation of the Space vector Pulse Width Modulation Technique

文章详细叙述了空间向量脉宽调制 (SVPWM)的原理 ,并结合 TI公司的 TMS32 0 F2 40 DSP介绍了基于软件和硬件实现 SV PWM的两种方法 ,总结了这两种方法的特点。最后 ,给出了 SV PWM的输出经滤波器后的波形。

This paper gives an in depth discussion of the principle and implementation of the space vector pulse width modulation technique.Two different SVPWM methods,one using the regular compare function on the Texas Instrument TMS320F240 digital signal processor and another implemented with the SVPWM hardware module on the TI TMS320F240 DSP are presented, and the characteristics of these two methods are summarized. At the end, the SVPWM waveforms with carrier filtered out are shown.
