| Abstract: | High power GTO inverter is used for railway electric traction.Its PWM control is significantly different from variable frequency drive system in conventional industrial area.Onthebasis oftheanalysis of the influence of the magnetic flux linkage deviation to the motor torgue ripple,in consideration of the technical features of PWM control of the high power GTO inverter,the paper explains the magnetic flux linkage locus PWM control rationale and realized method based on the zerovector carrier for railway electric traction,and the experimental results presented at the end of the paper proves that the control method is viable. |
