摘要
基于空间矢量调制的三相滞环电流控制器的外滞环宽度较小时不能有效的控制三相电流最大误差,针对这个问题,提出了一种改进滞环电流控制器,它在每一个区间内采用了三个有效电压矢量和零矢量来控制三相电流的变化,从而能有效的控制三相最大电流误差,简化了外滞环宽度的选择,降低了三相总开关次数;并做了仿真试验,试验结果也证明了以上其优点。
When the outer band of space-vector-modulation-based three-phase hysteresis current controller (HCC) is too small, the maximum current error can not be controlled.An improved HCC is put forward, which has the advantages of limited maximum current error,simplified choice of outer band and switching frequency by adding three effective voltage vectors and a zero vector in every region.The simulation and results show the advantages above.
