| 摘 要： | 提出了一种基于电压空间矢量的滞环电流控制方法.该方法将相电流误差通过滞环比较器得到3组电流误差矢量,并通过对电流误差矢量和参考电压矢量扇区的判别输出最优电压矢量,从而使电流误差控制在滞环宽度内.该方法能有效地消除相间影响,并且能够在较低的开关频率下有效地限制电流误差,既有较好的电流响应速度,又有较好的电流跟踪性能.设计...

| Abstract: | A hysteresis current control based on voltage space vector is proposed,which obtains three groups of current error vector by importing the phase current error to the hysteresis comparator and outputs the optimal voltage space by determining the distribution of current error vector and reference voltage vector.Therefore,the current error is limited in the hysteresis width.It can efficiently eliminate the interference and restrict the current error under a lower switching frequency.A fully digital control sys... |
