Abstract :
In this paper, a novel space-vector PWM control method of three-level converter is proposed. The effect of the motor´s phase current to DC voltage balance is analyzed in detail. After that, a new DC-voltage balance method is carried out. Compared to the conventional one, this method can adjust the DC voltage under all kinds of loads. At last, it is verified by experimental results
