Abstract:A novel simplified space-vector pulse width modulation(SVPWM) algorithm of a three-level inverter was ana-lyzed.The traditional space-vector module algorithm of a two-level inverter was applied to a three-level inverter based on DSP.Mathematical calculations of this algorithm were performed and its implement steps were showed.Taking a 22 kW three-phase asynchronous motor in lab and a 55 kW and a 1 000 kW three-phase asynchronous motor in field as experi-mental subjects,the experimental results of three motors testify the effectiveness of the simplified SVPWM modulating al-gorithm and it can get good performance in practice.
Keywords:inverter  pulse width modulation/three-level  digital signal processor
