Based on theoretical inference and computer simulation,the relationship between the harmonics and the parameters of SPWM was widely investigated.The rule of the total harmonic distortion and the harmonic spectrum distribution has been obtained.In order to decrease the harmonics,the selecting methods for optimal magnitude of the amplitude modularity and the frequency modularity are also given.
