| 摘 要： | 本文提出了一种基于最优电压空间矢量的有源滤波器滞环电流控制方法。该方法的特点是以相间电流误差而非相电流误差作为控制对象，因此可用三个滞环比较器构成参考电压矢量所在区别判别器，在此基础上应用最优电压矢量实行滞环电流控制。在同样的控制精度下，该方法可有效地降低开关频率，减小有源滤波器开关损耗。计算机仿真结果验证了这一方法的有效性。

| Abstract: | An optimized space voltage vector(OSVV) Based hysteresis current control method for active power filters is proposed. It is characterized that the control objectives are not phase current errors but inter phase current errors. With three hysteresis comparators which consist the detector of the reference voltage vector located region, optimized voltage space vectors are applied for hysteresis current controlling. With the same control precision, this method can effectively lower the switching frequency, reduce the switching loss and improve the performance of APF. It is also validated by the computer simulation results. |
