Abstract：An optimized control method for SVPWM in the voltage source inverter-induction motor system was developed to meet the requirements of experimental system of traction equipment safety assessment (ESTESA). The nonorthonormal basis is used to transform coordination. And then the time of the space vector is calculated through algebraic operation and the requirement of real-time is satisfied. The number of switch on/off is reduced through assigning the zero vectors. The performances of two kinds of the assignments of zero vectors are simulated in harmonic distortion, harmonic loss and torque ripple under different modulation. And then the optimized SVPWM is obtained in different environment. The method is verified in real system and the result show it is valid and has the advantage. The method has been used in the ESTESA system.
