Abstract Up to now, multiple switching angle curves (SAs) of selective harmonic elimination PWM (SHEPWM) have been obtained and provide control system of induction machines (IM) more SHEPWM strategies in railway driving. This paper mainly analyzes harmonic of different SAs and proposes key criterions, such as WTHD, for their optimization. Contrast experiments based on IM control system are carried out to verify their difference and optimization criterions. And the results agree with the theoretical analysis well.
