| 摘 要： | 三电平变流器工作于过调制区间时,由于中矢量作用时间较长,所以常规的过调制输出矢量顺序会引起较大的中点电压偏移与波动.常用的中点电压平衡控制在过调制区中应用可以抑制中点电压的偏移,但不能减小中点电压的波动.为减小过调制时产生的中点电压波动,提出了一种新的利用矢量合成的过调制输出矢量顺序,该方法可将中矢量的作用时间减小为常... |

| Abstract: | Common neutral-point voltage balance control technique can not decrease fluctuation of the neutral-point voltage but effectively eliminate offset of the neutral-point voltage.In order to decrease fluctuation of the neutral-point voltage,we present a novel output vector order of over-modulation using vectors synthesizing concept.The new method can decrease action time of the middle vector to 1/3 of the conventional over-modulation technology.Therefore,the method can reduce fluctuation of the neutral-point vo... |
