The Design and Implementation of SPWM Based on TMS320LF2407A

This paper introduces symmetry rule sampling algorithmic based on the digital signal processor TMS320LF2407A. By using the three full-compare units on event manager, the paper gives the method to generate the three-phase symmetrical SPWM wave form. As using the table look-up scheme, the system possesses high processing speed and good stability. Both some of the source codes and detailed Computational Method of the pulse width are presented. At last, experimental results show the satisfied wave.
