Abstract:In order to degrade the influence of dead-time, proposed a simplified space vector pulse width modulation (SVPWM) for voltage source inverter dead-time compensation method. Analyze the affection of dead-time effect to output voltage and power factor angle, after coordinate transform, by computing the related vector’s effective duty cycle of the reference vector in each SVPWM sector, we obtain dead-time compensation method and compare with the current waveform before and after compensation via DSP experiment instrument. The result of experiment verified the feasibility and correction of the compensation method. At high speed, the compensated waveform closer to the stander waveform; at low speed, the compensated waveform is more regular.
