Study of a Novel Dead-Time Compensation Method for SVPWM

摘要：

The dead-time effect in a three-phase voltage source inverter can result in voltage losses, current waveforms distortion and torque pulsation. In order to improve the current waveforms and decrease the torque pulsation, this paper analyzes the influence of dead-time on output voltage in detail, and proposes a dead-time compensation method of SVPWM, which through changing the traditional 180 degree turn-on mode into 120 degrees plus 180 degrees turn-on mode, thanks to the alternate use of the two strategies, the influence of dead time can be reduced to zero. The implementation is simple since only program needs to be modified comparing to traditional SVPWM technique, and by simulation and experiments results the correctness and feasibility of the algorithm are also be verified.
