In order to improve the current waveform and decrease the torque pulsation, this paper proposes a deadtime pensation method of SVPWM. This method divides the iα iβ plane into six sectors and pensates the deadtime of SVPWM according to the sector number of stator current vector determined by the α and βaxis ponents of the stator current vector in the twophase static reference frame. In addition, this method can be implemented entirely through software without any extra hardware. Finally experiments based on DSP TMS320F2812 are established and made, and the experiment results indicate that the proposed method is correct and feasible.
