Total harmonic distortion

The dead-time effect in a three-phase voltage source inverter can result in voltage losses, current waveform distortion and torque pulsation. In order to improve the current waveform and decrease the torque pulsation, this paper proposes a dead-time compensation method of SVPWM. This method divides the i <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">¿</sub> - i <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ß</sub> plane into six sectors and compensates the dead-time of SVPWM according to the sector number of stator current vector determined by the ¿- and ß-axis components of the stator current vector in the two-phase 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.
