Abstract Switch frequency harmonic produced by converter is an important interfering source. Combining low-pass filter broadly used, random factor can be introduced to SVPWM in order to restrain switch frequency harmonic. Two randomized methods are analyzed and compared. Switch period randomization has better restraining effect than plus position randomization. Randomized period SVPWM (RPSVPWM) is used in back-to-back converter. The comparative analysis verifies the validity and feasibility of the scheme proposed in this paper.

Key words： Switch frequency harmonic back-to-back converter randomized period SVPWM (RPSVPWM) EMI
